[Feature Request] set_tile_colors should accept multiple tile colors

[mclarkk]

Right now if tile_count > 1, the method will just duplicate the specified tile_colors across multiple tiles, which is how the LAN protocol message works. However, for the higher-level API, you should probably be able to give a list of tile colors that will get applied across the subset of tiles, or duplicated if there aren't enough colors for the specified tiles.
