2023 Update

- The default write type in buffer_write_auto is now buffer_f64, so instance ids are saved correctly.
- The game state functions now use a map for instance ids instead of a struct. This change was made in response to a slowdown bug with structs in GameMaker, but it may not be needed depending on what version of GameMaker you're using.
- with_synced_object now throws an error if you try to use it with an object that is not being synced.
- The default lobby timeout is now 360 frames instead of 300 frames.
- Got rid of unnecessary fonts.
- General code formatting changes.
- Changed copyrights to 2023 :)
