Implemented a parser for Euphony music. No
FM instrument support yet, as the FM chip used
by FM Towns is not being emulated yet. In the
meantime, a stock FM-emulated GM instrument is
being used instead.
This at least makes the Zak Towns kazoo tune
and the Loom Towns distaff audible. Emulation
of the FM Towns synth chip, or suitable
emulation using the OPL2 synth, is still
under investigation.
