Add special characters to system font

The font bitmap has empty space reserved for ASCII characters 0x80 through 0xA0.

We should use that space for something, like icons for WASM-4 controller buttons, or generic sprites like stars/hearts/etc.

Games can then use hex string literals to easily display these:

text("Press \x80 to jump!", 0, 0);

If anyone enjoys making pixel art and would like to modify the .png, I can follow up with updating the encoded images in the runtimes!

Here's a first go at possible glyphs.

I've posted a prettier, high resolution version in the Discord. As it stands, these additions would need to be revised, both in the choice of symbols and how they're drawn.

+1 on playing card suits - would be useful in a project I'm working on right now :)
