Sample code license

Suggestion: It's fine that the dithertron is GPL. But the sample code used probably should be MIT, or whatever (BSD2, or whatever). That way people can start their own projects using those assembly samples without GPL infecting everything they do.

I made a note that 8bitworkshop sample code is CC0, but forgot to here. I'll add those, thanks.
