Feature request: Soroban Cahoots from Trezor #368

With Soroban Cahoots and Whirlpool to xpub implemented all is missing is to spend privately from HWW.

According to @prusnak Trezor is ready to do that. I can't provide more information on what would it take personally, but I'm sure he would gladly advise on that.

Thanks! :)

More technical info about Trezor:

Trezor can sign external inputs via InputScriptType.EXTERNAL
each external input has to be accompanied by Ownership Proof defined in SLIP-0019
even more details are in the PR that added External inputs to Trezor: https://github.com/trezor/trezor-firmware/pull/1080

Sparrow uses HWI to communicate with Trezor, so it appears that progress will need to be made on https://github.com/bitcoin-core/HWI/issues/551 to support this.

Seems it's on the right path :) https://github.com/bitcoin-core/HWI/pull/590
