v0.22.3

Bump after a bit of a hiatus. Mostly housekeeping, but also a (rough) new crops system (can you tell what recent game we've been playing lately?)

• Outline fonts for better visibility (especially where colors are limited)!
• Script fonts for variety!
• Ability to grow crops (limited to the turnip seed you get from the princess, for now)!
• Animated sky in POV mode (looks weird, but it's a start)!
• Code cleanup (still inconsistencies, but some have been addressed)!
• Finally split up PalmOS version into different code sections.
• Bug and warning fixes!

Same caveats as always: binary data files not compatible between versions, etc.

WebAssembly builds:

• VGA
• CGA

Z key is "Start" or "Interact", WASD moves. Q in-world opens the main menu.
