In this commit, we extend the path finding to be able to recognize when a node needs the new TLV format, or the legacy format based on the feature bits they expose. We also extend the `LightningPayment` struct to allow the caller to specify an arbitrary set of TLV records which can be used for a number of use-cases including various variants of spontaneous payments.
