update ricochet to use hsv3
Is the Tor Project willing to adopt ricochet?
[[doc/TorifyHOWTO/InstantMessaging]] mentions/recommends ricochet. it uses v2 hs and would need to be restructured to support v3 hidden descriptors.
It is said to be stable and usable but receives no updates and ships an old tor version. Probably other changes are necessary as well, to fix possible security issues.
There is a ticket for it already and a WIP PR.
