if i understand the cashubtc/nuts#173 correctly, bunch of work to support amountless invoice will be handle by the mint, but here our createMeltQuote will accept an optional field, then check if the mint support amountless invoice, if YES, we refactor the MeltQuotePayload to have this

"options": { // Optional
    "amountless": {
      "amount_msat": <int>
    }

or better still, have a new method that handle amountless melt quote seperate from createMeltQuote
@Egge21M am correct here

I think it is fine to have it in one method, as it does not require an additional parameter. However the MintInfo class should be extended by a method to check wether this is supported
