[Driver] Converter-friendly driver with more detailed ADSR commands

[Chordian]

This would help to avoid overflowing the command table when converting from other players. They don't need to be anything else than note-focused for this purpose.

I think this should be put in a different major version driver and not 11.xx as it's something that the converter needs. The existing ADSR commands might even be replaced.

One command could handle everything. XX then have bits for nibble or byte as well as AD, SR or A, D, S or R, and YY then has the value that corresponds to that.
