use cereal for efficient serialization for wire format

I tried both binary and cereal. For a ActivityMessage that takes 341
bytes in JSON and has a dataSize of 129, both used 165 bytes. Went with
cereal since lazy bytestrings are not needed, and I might want to use
https://hackage.haskell.org/package/safecopy later.

(Perhaps I should be using protocol buffers or something to make it
easier for non-haskell implementations? But that would complicate things
a lot.)
