[Done 2.8] Phase Invert Button

Please! It’s the only basic processing function not available in the sample editor, and it is very important

Currently there is this tool: http://tools.renoise.com/tools/phase-invert-sample

But it’s the sort of basic function that should be integrated into the sample editor.

Here is the original feature suggestion from 2004(!) https://forum.renoise.com/t/trackdsp-phase-invert/14985


Massive thanks for adding this, Renoise continues to be the best thing I have ever purchased
