More fixes for regressions related to player message bubbles. Seperated `generateCharacter()` and `generateMessage()` functions for simplicity

Fixing another regression found during testing, user messages were breaking due to missing "playerName" attribute

Additional regressions caused by switching from UUID to player's display name (nick). Also, setting "born" and "death" timestamps, and no longer deleting chat data.

Refactor messages back to a single List<ChatMessage>, but now with a "name" attribute based on Player's display name. This will more easily allow for filtering the list of messages by player name, and also allow for more role playing (i.e. changing nick on a server can change your friendship / message history).

Limiting LEAD particles to 3, and move them further in front of the entity. Also scale LEAD particle smaller.

New animated lead particle (arrows pointing where they are going). New animated attack particles with random # of particles.

New follow, flee, attack, and protect particles & sound effects. Protect now auto sets friendship to 1 (if <= 0), to prevent entity from attacking and protecting at the same time. Passive entities no longer emit damage particles when attacking, they emit custom attack particles

Initial custom particles, and a custom particle type and factor for friendship particles (heart and fire)

Small refactor to playerData args, and a fix to prevent "" blank player from being in every entitychatdata. It should only exist with migrated data. Also made the old legacy JSON properties disappear after saving this new data structure.

More refactoring around PlayerData and player-based friendship. Also, adding in migration of data from entity-based friendship to player-based.

Large refactor of EntityChatData, EntityChatDataLight, and ChatDataManager. Separating these into smaller, individual files, to make it easier to maintain.

Switch from HashMap to ConcurrentHashMap to prevent an error when saving (while modifying the HashMap)

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
