New S2C packets to send whitelist / blacklist changes on login and after commands are executed. Chat Bubble rendering & interacting is now dependent on whitelist / blacklist config.

- Shader support (i.e. Iris, etc...)
- Updating CHANGELOG

Attempting to build for minecraft 1.20, 1.20.1, and 1.20.2. Replacing getLiteralString with getString, for compatibility

Adding client language into both prompts, so entities will attempt to speak in the player's language (if valid and possible).

- Raise player name when pending ... animation shown

- Click Handler no longer plays sounds
- Moved sounds to ClientPackets, so all clients play nearby sounds from the Chat interactions. Sound gets quieter with distance (0 to 8 blocks)

- Add new packet messages for Open UI, Close UI, and Sync UI status to the client
- Render ... animation above player heads who have the Chat UI open
- Added removed() method to Chat UI screen, so it always gets called, even when a player logs off
- Chat screen now sends messages to server with open/close status

Large refactor of clientPackets and serverPackets, to gather all network code into a more sane place.

- Filter out the current player if in 1st person, otherwise render their bubbles
- Refactor render code to better support missing chatData, for example a Player with no chatData still needs a name rendered

- Removing example mixins (from Fabric starter project)
- Replacing old screenshots
- Added Discord invite link to README

Reduce left side of click target. So left has 25% and right has 75% of the hit target. Make it easier for users to continue reading.

- Added player face to player chat bubbles
- Added placeholder player text-top UI graphic (no friendship)
- Reduced ticks visible per page of player messages
- Changed PlayerMessage to extend EntityChatData, for simplicity

- Added additional truncate logic, to ensure all messages are limited to 512 characters
- Added new PlayerMessageManager to keep track of currently visible player messages, to soon be displayed temporarily

- Broadcast this new playerId along with the chatData

- Clear previous messages, if character sheet is empty (i.e. test mode)
- Refactor out generate_chat() and generate_character() so they can be called from different packets more easily
- Don't allow chats with entities that have no character sheet generated - keep trying to generate a new character sheet (needed for test mode)
- Don't ever set "N/A" as an actual customName

- HIDDEN chat bubbles will become visible again when clicked again
- Added new setStatus packet to update chat status between DISPLAY and HIDDEN

- Added new keyboard icon - owlmaddie art, as a chat bubble at the end of a chat message
- Removed ChatStatus.END, and replaced the logic with isEndOfMessage() function

- Integrated this BubbleLocationManager into the ClickHandler, which fixes lots of issues and removes lots of duplicate code
- Rotate (yaw/pitch) of click handler geometry, so it matches exactly with the rendering locations/rotations.

- 2 debug methods added, to visualize click area and rays
- Now supports detection of TOP, LEFT, and RIGHT side clicks, based on where the user clicks in the chat bubble (for more UI options in the future)
- TODO: Still need to adjust the yaw and pitch of our 4 corners, so more extreme angles line up better with our detection.

Fixed entity heights for EnderDragon (lowered chat bubble) and fixed tilt calculation to use the padding above the entity height.
