Spend to Taproot

[bucko13]

Includes a few fixes:

• don't polyfill process env for trezor environment variables in @caravan/wallets
• cleanup some dependencies in @caravan/wallets
• remove unexported PSBTv0 modules from @caravan/psbt
• work to support bitcoinjs-lib v6 in @caravan/psbt
• Adding support to @caravan/psbt for taproot address outputs

TODO:

• [x] use new tx creation from @caravan/psbt to support paying tr addresses
• [x] new tooling for validateMultisigSignature which extracts the matching public key (?)
• [x] Fix failing tests
• [x] More changesets documenting the changes
• [x] Coordinator should have regtest support
• [x] Might need more robust address validation

NOTE: the diff looks a little bigger than it is because the tiny-secp256k1 library was vendor-ized. See updated readme in @caravan/psbt for more details

I'm still concerned with the major version increment I commented about on my previous review.
