Protocol request: open receipt / invoice data format

- Add a URL to a BIP-21 invoice, wallet grabs URL and parses receipt data
- Communicate a Nostr npub to the merchant, they DM the receipt data to you (to be consumed by your personal finance server at home)

Are there any standards out there? Can we make this happen?
