Ability to specify output file in osrm-extract

[flacombe]

Hi,

This would be great to add a -o --output parameter in osrm-extract to specify the path of the output file. Typical use case is to divert a single osm/pbf file into several osrm files (with different routing profiles).

It's currently mandatory to create at least symbolic links to my single osm file to make osrm-extract produce different osrm files. May I have miss some existing stuff regarding this ?

All the best
