Faster BeaconState enc/dec (#671)
* Add state enc/dec benches

* Add example for flamegraph

* Use `PublicKeyBytes` for `Validator`

* Ripple PublicKeyBytes change through codebase

* Add benches, optimizations to store BeaconState

* Store BeaconState in StorageContainer too

* Optimize StorageContainer with std::mem magic

* Fix rest_api tests
