Proposal to make cashu zaps where the payment itself is the zap (instead of waiting for a zap receipt from the zapper)

The sender locks a zap to the recipient's pubkey, optionally sending to a mint the user has recommended before (kind:38000).

Cashu is a bearer token so the receipt IS the money and the money IS the receipt.
