* Add PSBT QR code scan/show This PR introduces support to show and read PSBTs in BC-UR format via animated QR codes. This allows you to use BTCPay with HW devices such as Cobo Vault and Blue wallet to sign transactions without ever exposing the keys outside of that device. Spec: https://github.com/BlockchainCommons/Research/blob/master/papers/bcr-2020-005-ur.md I've also bumped the QR code library we sue as it had a bug with large datasets. * Reuse same code for all and allow wallet import via QR code scan * remove unecessary js vendor files * Allow export wallet from settings via QR * formatting * bundle * fix wallet receive bundle
