In this commit, we update the `HopIterator` to gain awareness of the new TLV hop payload. The default `HopIterator` will now hide the details of the TLV from the caller, and return the same `ForwardingInfo` struct in a uniform manner. We also add a new method: `ExtraOnionBlob` to allow the caller to obtain the raw EOB (the serialized TLV stream) to pass around. Within the link, we'll now pass the EOB information into the invoice registry. This allows the registry to parse out any additional information from the EOB that it needs to settle the payment, such as a preimage shard in the AMP case.
