Celeste 64: v1.3 Content Update (#4581)

### Features:

- New optional Location Checks
	- Checkpointsanity
- Hair Color
	- Allows for setting of Maddy's hair color in each of No Dash, One Dash, Two Dash, and Feather states
- Other Player Ghosts
	- A game config option allows you to see ghosts of other Celeste 64 players in the multiworld

### Quality of Life:

- Checkpoint Warping
	- Received Checkpoint items allow for warping to their respective checkpoint
		- These items are on their respective checkpoint location if Checkpointsanity is disabled
	- Logic accounts for being able to warp to otherwise inaccessible areas
	- Checkpoints are a possible option for a starting item on Standard Logic + Move Shuffle + Checkpointsanity
- New Options toggle to enable/disable background input

### Bug Fixes:

- Traffic Blocks now correctly appear disabled within Cassettes
