Pay to NPUB (P2NPUB) Proposal

This could be an easier way to transmit funds than zapping. The payer only needs to interact with a Lightning Address provider that supports P2NPUB. #Nostr and #CASHU take care of the rest.

P2NPUB is simply:

1. The LN Address provider detects that the local part of a LN address is a valid npub.

2. The LN address provider accepts the payment on behalf of the npub

3. The LN address provider then immediately mints a Cash token of corresponding amount (minus applicable fees)

4. The LN address provider sends by DM (NIP-04) to npub

5. Npub receives DM and redeems accordingly.

Already implemented for @openbalance.app

Any LN address provider can implement now.

Finally, LN wallets can easily support - it's just Lightning Address. If just a npub, just transform into a Lightning Address that supports P2NPUB.
