Liquid xpubs

[kilrau]

GDK should natively allow creating and exporting liquid xpubs. Some test vectors are already specified in https://github.com/ElementsProject/ELIPs/blob/main/elip-0150.mediawiki#test-vectors and https://github.com/ElementsProject/elements-miniscript seems to have added xpubs recently too.

We're planning to add support for it, but we need a elements-miniscript release first.
I think this will likely be early next year.

See https://github.com/Blockstream/gdk/tree/2023-09-25-liquid-watch-only for the ongoing work
