There were some bugs in the version I posted from my first attempt at removing stdlib and Stream dependencies.
This version works, at least for the testing I've done.

// ColorTable
// This class reads and writes color table files from disk.
// This assumes that the index color table is (at most) 256 colors long.
// If the file contains less, toString will pad with 0,0,0 entries.
