extra bytes prepended to (esp. json) output from santactl fileinfo ... --key <path> can be dropped?

I noticed that I'm getting extra bytes in the front of a string outputted from fileinfo's --key flag, and the inimitable @pudquick figured out it was in the color codes embedded in it. It definitely shouldn't be in there for json output, but I'd not expect colored output to be particularly useful for values returned with --key, either - more pressing is trying to use the python json module to .loads the value wasn't working for me.

It isn't?

santactl fileinfo --json --key Rule /usr/bin/yes
{
  "Rule" : "Blacklisted"
}

Au contraire mon frère, to my chagrin

#!/usr/bin/python
import json
import subprocess

path = "/Applications/WWDC.app"
cmd = ["/usr/local/bin/santactl", "fileinfo", "--cert-index", "1", "--key", "SHA-256", "--json",
       path]
output = subprocess.check_output(cmd)
with open("/tmp/jsony_output", 'wb') as outfile:
    outfile.write(output)

Aha: [2K is not a color code, it's the sequence for clear line. It's the only escape sequence I can see that isn't checking for JSON output or the presence of a TTY.

Tom's fixing now.
