Add internal compression to BRouter service call

[abrensch]

there's currenlty a size-limit of 0,5 MB for the resultng GPX in a service call to BRouter

To workaround that limit, I added a compression option to BRouter 1.5.x, where the GPX is gzip/base64 encoded internally.

For the client-side patch see this OsmAnd-PR:

https://github.com/osmandapp/Osmand/pull/7231/files

Could you implement this for Locus as well?

thanx, Arndt
