This update adds support to 1.17, however due to changes in NMS and a change in ProtocolLib, it would've been fairly difficult for me to keep 1.16 support, so I removed it, I expect most 1.16 servers will update to 1.17 soon anyways. If your server is still on 1.16 you can just stay on 0.8.2 for now, for now it's basically identical to 0.9.0 anyways.

Changelog v0.9.0:
- added 1.17 support
- removed 1.16 support
- updated Themis to Java 16 since it's required to run Minecraft 1.17 anyways
- fixed a rare bug that only happened when Viaversion is installed, that caused Themis to sometimes tp people to spawn
