v1.6.0 - Minecraft 1.19.4 support and fix minor bug when leaving chair
### Added
* Minecraft 1.19.4 support
### Changed
* Player no longer fall through the chair block when `TeleportPlayerToOldLocation` is disabled
### Breaking Changes
* `Chair#getPlayerLeavingLocation()` now takes `TeleportPlayerToOldLocation` into account
and produces a different result when it is disabled
* Should *probably* not cause any trouble for other plugins using the API
