Wave editor envelopes

[d.healey]

An idea I had for the wave editor while you're working on it :)

Would is be possible to add pitch and volume envelopes/tables? These would allow us to adjust the pitch and volume of the sample over its duration to even out any drift or to create certain effects like fade outs.

If these envelopes would add too much overhead to be played back in realtime by the sampler engine then I think it would be fine to have a button that destructively renders the envelopes into the samples, or this could just be done at the monolith conversion stage to make it non-destructive to the original waves.

Making it possible to grab these envelopes/tables via scripting alongside all the other sample properties we have would good.
