Properly handle and test sortedmulti descriptors

[achow101]

Implements better handling of sortedmulti descriptors. This is an API breaking change as display_multisig_address is changed to take the underlying MultisigDescriptor directly instead of the parameters stored within it.

For BitBox02 and Coldcard, since they only use BIP 67, they now require sortedmulti descriptors only.

For Trezors, sortedmulti is now being handled correctly. If a sortedmulti is provided, then the keys will be sorted appropriately prior to being sent to the Trezor for handling.

Lastly, tests are added to test both multi and sortedmulti, as well as both hex pubkeys and xpubs.

Fixes #487

moar tests 👍

@craigraw mind testing this to see if any more issues pop up?

Confirmed sortedmulti is working on Trezor, Coldcard and Bitbox02 using hwi.py. Using multi works on Trezor, and fails on Coldcard and Bitbox02 with an appropriate error message.

Oddly enough I can't seem to get a fully working binary from this branch - when communicating with the BitBox02 (for example with enumerate) the binary from contrib/build_bin.sh returns
