How do I interact with wavetable programmatically?

[turian]

Is your feature request related to a problem? Please describe!

I'm experimenting with creating new synths programmatically, that involve inserting custom wavetables. However, it is not clear how to do this in Surge.

Describe the solution you'd like:

1. Ideally, there would be an XML format that captures the complete state of the synthesizer, nothing missing (Update patch file format to not use .fxp #6627)
   The test suite for this could have scripts to roundtrip from FXP to XML and back, to make sure they are identical. I would be happy to contribute.
2. The Python API could be extended. If it is incomplete, an XML solution would be preferable.

Describe alternatives you've considered:
IDK.

Additional context:
I've made a lot of progress in getting AI to program synths, which I'll be sharing with the community soon, but wavetables is a missing link.

@mkruselj writes "if you check the scripts/patch-tool folder you will see how you can read FXP", so I'll close for now

And scripts wt-tool has full wavetable round trips

The fxp is an envelope some xml for everything except the wavetable binary, and the wavetables.
