Some of the JSON messages fedone's websocket API outputs aren't valid
json. For history hashes, fedone outputs strings like this:

"history_hash": "\262\323_Q\3001\0335\234\272\030 \370\311\'ERQ\266\026"

\123 is an invalid JSON escape sequence. (UTF-8 characters should be
encoded with UTF-8 or \uXXXX).

The data in question is a protobuf byte array. If the JSON parser
wants a way to encode byte arrays, it should probably be using either
base64 encoding or arrays of integers.

Its a known issue with protobuf-java-format[1], though I don't know
how long it'll take them to do something about it. I can't even hack
around it in my code because its my JSON parser which is kicking the
bucket. (And if I'm fixing someone's JSON parser, I'd rather fix
protobuf-java-format).

The sooner we can clean up (rewrite?) the JSON-protobuf gubbins in
fedone the better.
