Feature description

Hi, would be awesome to have a method in WebLN to pay multiple invoices with one prompt request. This can improve the a lot the UX of nostr zap splits without the need of set a budget.

Describe the solution

Add webln.sendMultiPayments(invoices: string[]) method. Internally: decode the invoices, calculate the total amount and prompt a payment request showing the total amount (an eventually a badge/description saying that is a multi-payment request).

Describe alternatives

Hi @yukibtc

We are currently working on this in the NWC spec, so maybe it can then be proposed to be added to WebLN.

Specifically the response needs to be reviewed because with this endpoint there is possibility of some payments succeeding and some failing. Any feedback there would be appreciated!
