Add `test_reject_invalid_min_final_cltv_delta` which is supposed to test that the peer rejects incoming htlcs with final cltv delta differing from what has been requested in the lightning invoice.
Adds the min_final_cltv_delta value to PaymentInfo so that it is possible to verify it later when receiving the htlcs in lnpeer. Currently the min_final_cltv_delta which was used in get_bolt11_invoice for the lightning invoice was not persisted (except maybe through the invoice in a Request object), so it was not possible to verify it when receiving htlcs. get_bolt11_invoice is now dependent on PaymentInfo being available, so PaymentInfo has to be created first. This is done to prevent creating a bolt11 invoice with different min_final_cltv_delta than the value stored in PaymentInfo.
Version 60 to 61, converts the PaymentInfo tuple into the PaymentInfo dataclass.
This ensures that invoices can only be created if PaymentInfo has been created first. It also ensures that the values in PaymentInfo are similar to the values shared in the invoice.
Enforces the min_final_cltv_delta and expiry the receiver of the payment has requested from the sender through the lightning invoice.
Test that lnpeer is rejecting incoming htlcs for invoices that are already expired.
Test that lnpeer rejects incoming htlcs for payments that have already been paid so invoices cannot be paid twice.
Reject new incoming htlcs for requests that have already been paid before.

Fixes some todos in
LNPeer.maybe_fulfill_htlc().min_final_cltv_deltarequested in the lightning invoice for incoming htlcs that will not get directly settled, this is relevant for hold invoices.This PR will do a wallet db upgrade!
