Add train routes into the system

[kernelshreyak]

Test first on QGIS with vector layer or GeoJSON of railway routes

Indian railway stations and routes data in GeoJSON tested on QGIS

[kernelshreyak]

Need to have an algorithm which can return the route based on arrival and departure stations extending over 7536f24

The routes are in the GeoJSON which need to be matched and queried based on coordinates of arrival and departure stations. The route should be an array of coordinates similar to other vehicle types.
Since matched routes will likely be an array of LineString data, it needs to be compacted into 1D coordinate array

As per the updated stations GeoJSON, update the train routing algorithm to use exact matching instead of nearest distance because stations will always lie on one or more linestrings

Routing algorithm is improved in 5b354f6
But, destination and arrival station selection is not accurate yet. Maybe need to sort the stations array to better get lowest distance match more accurate.
Also, the route found is not optimal (this will be handled in new issue)
