Tool to convert Sprite Sheet in PNG to HEX file that can be loaded as a resource

[plattysoft]

Aseprite can export a png sprite sheet, but msxbas2rom prefers to import binary hexadecimal files (compressed with pletter). This would be the most convenient way to work with sprites if we had such a tool.

Similar code examples exist, so it should not be too complicated to do

Combine the PNG reader for sprites from RetroDeluxe and the hex output from nMSXTiles into a command line tool that reads a png and creates a sprite sheet, actually, nMSXTiles does png parsing too
