Chat Tweaks

This could be considered the actual initial release since the first one wasn't actually functional.

• Fixed the mod to actually work outside of development environments
• Made the timestamps smarter with the ability to group them within a certain time frame (configurable)
• Made alternating message highlights smarter by grouping the highlights for each message, so messages that span across multiple lines will have the same highlight
• Fixed options not having descriptions
• Modmenu is no longer a forced dependency
• Fixed timestamps being visible when chat screen isn't open (and alwaysShow is disabled)
• Narrowed minecraft version support to be between (including) 1.21.2 and 1.21.3 instead of 1.21.3 and above to future-proof updates (currently not very useful)
