Finally getting back to do some KXStudio repository updates.

First order of business, cleaning and updating the basic libraries
https://launchpad.net/~kxstudio-debian/+archive/ubuntu/libs/+builds?build_state=all

The LV2 stuff changed from waf to meson, the deps are very sequential so it takes a while to confirm successful builds. The stack is basically:

zix -> serd -> sord -> sratom -> lilv

Updating PawPaw project (for easy win/mac/wasm static builds) along the way to match

That pretty much takes away my Sunday 😅
