Dustin Brody c53de3e550 Caching updates/refactoring & state_sim defaults updates (#235)

* doAssert a couple of constant relationships necessary to avoid underflow; rm non-spec, unused helper function get_new_recent_block_roots

* refactor separate crosslink_committee_cache and winning_root_participants_cache(s) into StateData object; remove last vestige of previous shuffling cache

You'll need the latest versions of nim-eth-p2p, nim-serialization
and nim-json-serialization.

Before starting the simulation script, make sure to delete any previous
json files from the simulation folder:

```
rm tests/simulation/*.json
tests/simulation/start.sh
```

This should survive the creation of few blocks before diying with a
block validation error.
