COLDCARD Q v0.0.6 beta
- bugfix: randomize keys for PIN entry
- when picking files, we just skip to showing you the files options (or picking the
single winner) rather than talking about it first.
- BIP-39 passphrase process completely streamlined
- batch signing now offered when we see two or more signable PSBT's on the card
- bugfix: can now reformat SD card in B slot
- move away from `44'` (prime) for hardened derivation paths, in favour of `44h`; both accepted
for input, but we are going to display `44h` style going forward.
- bugfix: (QR) or other double-wide chars would be garbled if half off right edge
- cleanups, bugfixes
