switch wire message seralization to use protocol buffers

This way it's not tied to details of the haskell binary library,
and implementations in other languages should be fairly simple to do.

The haskell protobuf library was used because it does not need extra
tooling or build steps. So I didn't write a .proto file, but one could
fairly easily be written by following ProtocolBuffers.hs and translating
it.

ProtocolBuffers.hs is *extremely* repetative and tedious code. Surely
there must be a way to not need to write all of that? Oh well, I wrote
it..

Sizes of serialized messages:

">>> debug-me session started": 121
sending a single key press: 169

This seems equally as efficient as the binary serialization was;
that was 165 bytes before elapsedTime was added.
