A tool to create SNES palette and sprite data.

In the process of working on Super Sherwood Showdown, I wrote a p5.js app to build spritesheets and palette data from image files.
It converts a 1x16 image into a SNES format 15-bit palette that can be downloaded as a bin file. It also converts 128 x 128 sprite sheets into indexed colours, then to SNES character data.
