Prepare 5.23.0 release

We fix this by checking for empty heaps before proceeding with
the search.

+## Flatbuffers format
+
+Default response format is `json`, but OSRM supports binary [`flatbuffers`](https://google.github.io/flatbuffers/) format, which 
+is much faster in serialization/deserialization, comparing to `json`.
+
+The format itself is described in message descriptors, located at `include/engine/api/flatbuffers directory`. Those descriptors could
+be compiled to provide protocol parsers in Go/Javascript/Typescript/Java/Dart/C#/Python/Lobster/Lua/Rust/PHP/Kotlin. Precompiled 
+protocol parser for C++ is supplied with OSRM.
+
+`Flatbuffers` format provides exactly same data, as `json` format with a slightly different layout, which was optimized to minimize
+in-transfer size.
+
+### Root object
+
+Root object is the only object, available from a 'raw' `flatbuffers` buffer. It can be constructed with a following call:
+
+         auto osrm = osrm::engine::api::fbresult::GetFBResult(some_input_buffer);
+
+**Properties**
+
+- `error`: `bool` Marks response as erroneous. Erroneus response should include `code` field set, all the other field may not present. 
+- `code`: `Error` Error description object, only present, when `error` is `true`
+- `waypoints`: `[Waypoint]` Array of `Waypoint` objects. Should present for every service call, unless `skip_waypoints` is set to `true`. Table service will put `sources` array here.
+- `routes`: `[RouteObject]` Array of `RouteObject` objects. May be empty or absent. Should present for Route/Trip/Match services call.
+- `table`: `Table` Table object, may absent. Should be present in case of Table service call.
+
+### Error object
+
+Contains error information.
+
+**Properties**
+
+- `code`: `string` Error code 
+- `message`: `string` Detailed error message
+
+### Waypoint object
+
+Almost same as `json` Waypoint object. The following properties differ:
+
+- `location`: `Position` Same as `json` location field, but different format. 
+- `nodes`: `Uint64Pair` Same as `json` nodes field, but different format.
+
+### RouteObject object
+
+Almost same as `json` Route object. The following properties differ:
+
+- `polyline`: `string` Same as `json` geometry.polyline or geometry.polyline6 fields. One field for both formats. 
+- `coordinates`: `[Position]` Same as `json` geometry.coordinates field, but different format.
+- `legs`: `[Leg]` Array of `Leg` objects.
+
+### Leg object
+
+Almost same as `json` Leg object. The following properties differ:
+
+- `annotations`: `Annotation` Same as `json` annotation field, but different format.
+- `steps`: `[Step]` Same as `step` annotation field, but different format.
+
+### Step object
+
+Almost same as `json` Step object. The following properties differ:
+
+- `polyline`: `string` Same as `json` geometry.polyline or geometry.polyline6 fields. One field for both formats.

+# Building OSRM for Windows
+
+## Dependencies
+
+Get a decent Windows with decent Visual Studio (14 at least for C++11 support). The published binaries are build with
+VS2019 and Windows SDK8.1.
+
+In case you are using [prepacked Windows VM with VS2019](https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/), you
+have to install [Windows SDK 8.1](https://go.microsoft.com/fwlink/p/?LinkId=323507)
+
+Prepare directories for dependencies, build and target file location.Target directory ($target starting from that moment) should have /include and /lib subdirectories.
+
+### Bzip2
+
+1. Download either from Wolt OSRM mirror or original distribution and unpack.
+    * https://project-osrm.wolt.com/deps/bzip2-1.0.8.tar.gz
+    * https://sourceware.org/pub/bzip2/bzip2-1.0.8.tar.gz
+
+2. Start 'x64 Native Tools Command Prompt for VS2019' and change directory to unpacked source tree.
+3. Issue `nmake /f makefile.msc`
+4. Copy bzlib.h to $target\include and libbz2.lib to $target\lib
+
+### ZLib
+
+1. Download either from Wolt OSRM mirror or original distribution and unpack.
+    * https://project-osrm.wolt.com/deps/zlib-1.2.11.tar.gz
+    * https://www.zlib.net/zlib-1.2.11.tar.gz
+
+2. Start 'x64 Native Tools Command Prompt for VS2019' and change directory to unpacked source tree.
+3. Switch to `contrib\vstudio\vc14`
+4. If needed, open `zlibvc.sln` with Visual Studio and retarget to your version of compiler and SDK.
+5. Issue `msbuild zlibvc.sln /p:BuildInParallel=true /p:Configuration=Release /p:Platform=x64 /m:<Number of cpu cores>`
+6. Copy x64\ZlibStatRelease\zlibstat.lib to $target\lib\libz.lib, copy zlib.h and zconf.h to $target\include
+
+### ICU
+
+1. Download either from Wolt OSRM mirror or original distribution and unpack.
+    * https://wolt-project.wolt.com/deps/icu4c-66_1-src.zip

+    * https://github.com/unicode-org/icu/releases/download/release-66-1/icu4c-66_1-data.zip
+2. Do retarget if neededby openinig .\source\allinone\allinone.sln and editing projects
+3. Start 'x64 Native Tools Command Prompt for VS2019' and change directory to unpacked source tree.
+4. Run build:
+    msbuild .\source\allinone\allinone.sln /nologo /p:BuildInParallel=true /p:Configuration=Release /p:Platform=x64 /m:<Number of cpu cores>
+5. Copy lib64\*.lib to $target\lib, copy include contents to $target\include
+6. Copy bin64\*dll to any dir withing your $PATH. At the same time copy them to $target\lib
+
+### Boost

+2. Start 'x64 Native Tools Command Prompt for VS2019' and change directory to unpacked source tree.
+3. Lua doesn't have native MSVC support, so you have to compile it by hand:
+    cd src
+    cl /MD /O2 /c /DLUA_COMPAT_5_2 *.c
+    ren lua.obj lua.o
+    ren luac.obj luac.o
