This removes the dependency on the QrEncode lib and uses
the fact that our scanning lib also is capable of making QRs.
We now allow the QR to get its color inverted for dark mode
users, making it less bright to show a QR.
This introduces a new QR-creation mode which allows spaces and
other chars to be in there directly without being URL-encoded.
This improves the QR showing of the user's seed-phrase (in the
backup screen).
This adds the ability to scan a seed phrase with your camera by
adding a button to the wallet import page.
This also adds support for the QR format that the bitcoin com
wallet uses in its QR for seed phrases.
