Porting Synth_Dexed to Windows, Linux, and macOS

[probonopd]

Synth_Dexed by @dcoredump is the synthesizer engine that powers MiniDexed.

From time to time, we run into questions like "is this a Synth_Dexed issue", etc.

Hence I thought it might be beneficial to port Synth_Dexed to Windows, Linux, and macOS.

Also, to automate things, I thought it might be beneficial to have Python bindings (so that we can script Synth_Dexed from Python).

So... here we go:

• Windows is tested
• Linux is to be tested by me soon
• macOS cannot be tested by be since I have no hardware capable of running recent versions of macOS. So I'd appreciate if someone could give it a try
• Teensy still builds but cannot be tested by me since I have no Teensy hardware. So I'd appreciate if someone could give it a try

Well... it was bound to happen at some time. I guess here we are:

I thought it would be neat to be able to play Soundplantage performances (and in the future possibly other types of performances as well), on Windows, Linux, and macOS.

So the idea of FMRack was born. (Think of it as the core of MiniDexed minus the GUI, but running on top of an operating system.)

If this experiment turns out to work well (and so far it is looking promising), then I could imagine it to become part of a future MiniDexed 2.0 that might use a tiny Linux (basically just the kernel and not much more) + FMRack + a user interface (be it with small or large displays). This would resolve, amongst others:

• MiniDexed on "normal" OS #598
• Does it work on Raspberry clones? #484
• MiniDexed on a Le Potato? #410

I'd appreciate your thoughts on the FMRack architecture and implementation.
