feat: QR scanner should handle dynamic QR codes

It would be needed to work with offline e-cash notes after the support of MutinyWallet/mutiny-node#1024

@futurepaul @benthecarman @benalleng I will try to give it a try after MutinyWallet/mutiny-node#1024, but do you have any thoughts on this already ?

We use this library https://www.npmjs.com/package/qr-scanner not sure if it has support for animated QRs. Would rather not have to move to a different library for this

[benthecarman]

Maybe we figure out NFC support and only do OOB notes through that

Cool, I'll take a look at this library

Yes, that's a good approach as well

btw I was taking a better look at it and it's seems it's not supported nimiq/qr-scanner#65

but even before the NFC support, we would need to have support for issuing oob notes / offilne ecash
otherwise, there is no other wallet issuing ecash with NFC support 😅
