Bedrock Support

I tested the setup with Geyser, and it is almost 99% compatible with Bedrock, except for the following issues.

1. Floating Heads: They do not appear on Bedrock clients because they use Display Entities, which do not exist on Bedrock but still clickable.
2. Holograms from FancyHolograms: Similar to Floating Heads, they do not display. Use DecentHolograms to fix this.
3. Custom head item textures inside GUIs are mostly not displayed. This is normal.
4. Many Java HEX colors will not display correctly on Bedrock and will be converted into different colors instead. This is normal.
