Add support to handle exploded data

[vladtr]

As it was noted in #1280 regarding get_transaction_id api call by @heifner, following are desirable set of improvements in a way data / hex_data is being handled.

Copy/pasting original description from mentioned above PR:

• As part of this effort, I think we should support exploded data.
• As part of this effort, I think we should provide optional support for exploded data in cleos. For cleos, this should be optional as a user may want to prevent cleos from communicating with nodeos. Could support the option of providing abi. See --unpack-action-data option --abi-file.
• To increase security, if both "data" and "hex_data" are provide then we should verify they are equivalent.

This was initially added to track potential additional logic to protect the user from being deceived by false transaction json. After discussion, we determined that these additional protections are not necessary based on the intended purpose of the get_transaction_id api call.
