Add support for recurring payments

[raweber42]

Currently, it doesn't seem that recurring payments to the same order are supported. For us at lipa, this is a essential part of creating an order, as our users like to setup recurring payments. The way our implementation works, we cannot provide a quote upfront. The exchange happens only once the money arrives in our company bank account.

We should be able to place an order such that the user can use the same order to make several payments in order to DCA (Dollar cost averaging).

Is anything like this planned to be added to this spec? We are open to contributing.

@raweber42 LSPS1 doesn't require quotes, it only supports them

if you look at https://github.com/breez/fiatlink/blob/main/FLS01/README.md#quote there is ìs_estimate field in the reponse:

• is_estimate can be true or `false,at discretion of the provider if he wants to provide a short duration binding quote or estimate

So your requirement is that the order id is persistent - at least the way user sees it? Is that for direct debit or automated credit card payments scenario?
