C65 CPU support

[fachat]

IF the C65 really needs a new CPU definition, use CPU2 bits %0110

But is it really needed?

I've made an .o45 format which is pretty much the extension and answers if it's needed. :-) See : https://github.com/CTalkobt/m65compiler/tree/main. See: https://github.com/CTalkobt/m65compiler/blob/main/doc/lib45.md
