liana v9rc1 and krux pull/498
when recovering an expired utxo (taproot, single primary key, single recovery key after(6)):
- can update w/krux's sign-to-sdcard and broadcast
- can update w/krux's sign-to-qr but cannot broadcast: complains "422: failed to finalize PSBT"
- can copy from liana after above error, delete psbt, import from clipboard and broadcast w/o error

diybitcoinhardware/embit.bip39.mnemonic_to_bytes() speedup
In the spring of 2024, while brute-forcing mnemonics, I took a look at improving the performance of embit.bip39.mnemonic_to_bytes(), which is:
- well peer-reviewed
- tested... arguably enough
- stable and in-use by a number of projects
I ended up re-implementing this function using a big-integer accumulator. I call the branch "bip39_via_accumulator".

Completely untested with actual qrcodes: based on fact that python's set.symmetric_difference is analogous to XOR.
This is an exploration of extrapolating more XOR-mixed frames than have been received while reading a fountain qrcode.
ie: If we get 2 frames with parts [0, 1, 3, 5] and [3, 5, 7, 9], then we also have [0, 1, 7, 9]
