Priority Tokens for Root AI

Priority tokens for when using the AI, and you have to look up the reference card all the time. These tokens can be placed on the map instead for easy reference, with a shape that doesn't conflict with square or circle tokens already.

Two versions:

• Multicolor print: uses 3 files: Frame, Numbers and Infill.
• Single extruder: just use layer height to pause print and change filament: Single Extruder.
