Taproot signing - tapBip32Derivation unsupported

[rolznz]

Hi,

I am trying to sign a simple taproot PSBT transaction generated by sparrow wallet (one input, 2 outputs) and I hit this error:
if (input.tapBip32Derivation) throw new Error('tapBip32Derivation unsupported');

Is this planned to be implemented?

Thanks!

Would be nice to have, but no immediate plans.

Is this issue also fixed with #101? Would love to see it included in a release.

My use case is that I'm using bip32Derivation/tapBip32Derivation as a way of passing which key to use metadata when handing off a PSBT to another part of the code to do the signing.

yeah just need to fix npm run build
