Implement https://github.com/frostr-org/bifrost into your signing flow (as an option)

We are also working on nip46 frostr bridge soon (so that client devs will have less work to do to support)

https://github.com/frostr-org/frost2x is example for client devs wanting to support frostr in nip-07 signing flow

I think NIP-46 is the best way to do it. We can make a NIP-46 bridge for igloo / permsfrost, then a PWA remote signer version of frost2x.
