[Tagging] oneway=reversible and conditional restrictions

[Richard]

Hi,

some time ago there was a discussion how to tag this. The good news
is that OsmAnd developers worked on implementing it, so it might actually
work:)

Unfortunately I don't have the possibility to check it myself now,
if you are interested have a look at 

https://wiki.openstreetmap.org/wiki/Tag%3Aoneway%3Dreversible
https://github.com/osmandapp/Osmand/issues/6271

Apparently the impact is much more than just oneway=reversible
as conditional restrictions are now "implemented" in OsmAnd.
