More options for the ZX Spectrum buzzer

[andrelisboa1]

I think a good feature would be allowing for different engines for ZX Spectrum 1-bit beeper music, like Tritone, Huby, among others.

[freq-mod]

these are actual z80 routines controlling the beeper. alternate zxbeep drivers are not planned now, unless someone adapts them into furnace's architecture and pull requests them (maybe I will try in the future?)

[tildearrow]

Furnace currently doesn't emulate the Z80, necessary to run these drivers.
Furthermore, there are plenty of incompatibilities that I may hit during the process.

May consider in the future though.

Shiru's great 1-bit tracker, adapts these engines via scripting, AngelScript, but yes, Z80 emulation is needed. But having 1-bit tracker integrated in Furnace's modern GUI would be really nice :D, those 1-bit engines have a soo special kind of timbre/tone :D
