Cast data into prepare_tx50 into int, order data for hex processing, return byte stream on conclusion of prepare_tx50() and break up code into 3 methods, prepare_tx50, construct_packets, and build_transaction().
Make mastercored a hard requirement for issuing assets. Make 'transaction_from' a required field. Change method signatures to be more generic, add TX51 logic for prepare_txbytes(). Use TX51 method of hex byte packing.
Refactored explorer routing and controllers to support assets management only when logged in
