6. Improve heuristic hex transaction decoding

   Whenever both encodings are permitted, try both, and if only one succeeds,
   return that one. Otherwise prefer the one for which the heuristic sanity
   check passes. If that is the case for neither or for both, return the
   extended-permitting deserialization.
