Add TransactionTests wrapped as Go tests

* Add initial go wrapping for TransactionTests with some tests
  disabled in lieu of consistent HEX encodings and a few other
  pending bugfixes
* TODO: Consider better way of perhaps modelling each test in
  the JSON files as a single Go test, instead of one Go test per
  JSON file
