separate out benchmark into 4 stages: create, serialize, deserialize, hash

As mentioned in #153. This gives us a better overall picture of where time is going, in the various modes.

Nice, thanks :)

I merged this with master - note that now the deserialization shows as being incredibly slow for regular classes deserializing from JsonBuffers which is interesting (it wasn't measured at all previously!). Investigating this would be some additional work, clearly something pathological is happening.

[jakemac53]

Actually, the slowness looks identical to what happens if you do the hashing benchmark by iterating the keys and looking them up - which is how I implemented the deserialization. So, it makes perfect sense.

Sorry, I intended to approve with the review ... apparently I still fail at GitHub.
