Release v9.2.1 - Multi

Release notes:

• New features:
  • Support for legacy segwit multisig. It uses legacy 3... addresses for backwards compatibility with services that do not yet support bech32 bc1... adresses.
  • Sign Bitcoin messages
  • Added a screensaver. It activates after ~1min of inactivity. Thanks @My1 for contributing the bouncing logo animation.
  • When signing a Bitcoin transaction, a progress bar now indicates progress when loading and signing the transaction.
  • Multisig account verification: allow verification of the xpubs in xpub... format instead of Zpub... or Ypub... formats
    Signing multi-line messages can now be verified more easily as each line is verified individually
• Autocomplete BIP39 words when restoring from recovery words (mnemonic)
• Allow editing previously entered words when restoring from recovery words, to fix typos
• Dropped the word bech32 from the receive screen.
• "Unlock device" screen can now be cancelled.
• Ported API calls to Rust: DeviceInfo, DeviceName, SetPassword, Reset, SetMnemonicPassphraseEnabled, InsertRemoveSdcard, CheckSdcard, CheckBackup, CreateBackup, ShowMnemonic
• When using U2F on a website that is unknown to the BitBox02, instead of a long and cryptic "unknown site" identifier, four mnemonic words are shown instead, e.g. slogan tone around chicken. This makes it much easier to recognize the same site in the future. Thanks to @My1 for this contribution.
