Support MIDI detune parameter

[Spacechild1]

I've tried the sfizz v1.2 VST3 plugin and it doesn't seem to implement detuning of MIDI events via the Steinberg::Vst::NoteOnEvent::tuning member.

The VST2 version of sforzando by Plogue, on the other hand, does support detuning and it's lots of fun :-) (Curiously, the VST3 version does not, which must have been an oversight.)

I've tested with my VST plugin host for Pure Data and SuperCollider (https://git.iem.at/pd/vstplugin) which implements the tuning parameter via fractional MIDI note values.

Just to second this request. Actually I'd consider poking around at it --

Here seems to be limited to straight up char note numbers: https://github.com/sfztools/sfizz-ui/blob/develop/plugins/vst/SfizzVstProcessor.cpp#L373

noteEvents[numNoteEvents++] = std::make_pair(key, value);

So the note-event interface would need to be extended? As well as sfz::MidiState::noteOnEvent.

Well... "nobody is using that" but I do, and it would be a way for sfizz to jump ahead of other samplers.
