Once the codec is finished and reviewed, we can add LND to the deserialize_offer target.

Thanks for the PR @usefahmed07 !! It seems that #654 is not implementing the deserialize_offer target for LND.

My bad, wrong PR link! #654 is just two unrelated bug fixes, not the target.

The real deserialize_offer target is in #655 — it's a draft for now since it depends on lightningnetwork/lnd#11199 getting merged first. Thanks.
