Implement raster source feature to read data from third-party sources, to be used in lua profiles.
* Adds a data structure, RasterSource, to store parsed + queryable data * Adds bindings for that and relevant data structures as well as source_function and segment_function * Adds relevant unit tests and cucumber tests * Bring-your-own-data feature
