Round Robin + Group XFade

[d.healey]

@Simon It's an interface issue I think. Click this XFade on button and you'll see a table for every group. However setting them all individually seems like a nightmare so I would add a script to your project with however many tables you need, let's say you have 3 dynamics, so 3 tables. And through the magic of scripting use those to set the xfade tables for all the RRs.

Ignore that, looks like Christoph already foresaw this issue - https://docs.hise.dev/scripting/scripting-api/sampler/index.html#setmultigroupindex
