Provide ability to decode serialized responses

We transport data using binary protos. Unfortunately, this means that responses look, for lack of a better term, like garbage in Stetho when using this plugin :(

Would it be possible for us to encode the responses in Dart before they get sent to the platform channel? It would probably have to be done at a higher level than HttpOverrides as we don't know the expected format in order to deseralize the data there.

Start by tracing how this Dart plugin handles responses before they cross the platform channel, then determine where serialized response data could be decoded without relying on an unknown format. Done means binary-protobuf responses are readable in Stetho, but the issue does not name files, tests, or a specific serialization format.
