Increase PackedOSMIDs size to 34 bits

Browse Source 
OSM node 2^33 was created in early April 2021. This and all
subsequently created IDs will be overflowing OSRM node storage
which only support 33 bit IDs.
Bump the number of bits to 34 to double node ID capacity. This
is a breaking change to the data format as it alters the layout
of .osrm.nbg_nodes.
