Hey, thanks for the PR. I'd like to merge it but it seems none of the example inputs work. Could you fix up the remove_metadata function so that they work?

(venv) ~/src/rattle(solc*) » python3 rattle-cli.py --input inputs/kingofether/KingOfTheEtherThrone.bin -O
Traceback (most recent call last):
  File "rattle-cli.py", line 202, in <module>

Hi. I forgot to update the example inputs. I remove the extra step of converting the result of solc --bin-runtime to bytes. That's why you got the error.
