C128 voice synthesis using z88dk

[sgjava]

I've ported all of my SID code over to z88dk. Part of that is voice synthesis using the ARPAbet. 4 bit phonemes sound as good or better than SAM if you remember that. 2 bit and 1 bit obviously not as good. I've built all the tooling to take phonemes, convert them to RAW PCM format and compile into a singe file (phoneme library). Boot CP/M then mount https://github.com/sgjava/c3lz/blob/main/disks/talk.d71.

More cool C128 stuff to come.

Sorry for taking this long before answering, it is a fantastic result, I'd really love to have it merged into z88dk.
