there are a few ways to implement this so wanted to add color to my choices. happy to change -

• to construct the reveal_pk transaction body, the code calls out to a helper submit_reveal_aux
• this method has some internal complexity and is used elsewhere so I dont want to change that function
• so I chose to isolate the complexity here to just the reveal-pk subcommand and call out to build_reveal_pk directly when users request to get the raw tx json

we don't need to look-up the PK as we already have it in args.public_key
