Zahary Karadjov 8f9a5441f1 More reliable network simulation
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.

hash_ssz: updates (#13)
* rename from tree_ssz
* add special cases for some types based on beacon chain code
* add smoke test
* avoids some trivial allocations, but the big one remains - the

* update to handle zero-length buffer case same as latest spec

Signature aggregation in block processing (#5)
* signature-aggreg-in-block-processing

* Message is a Blake2 hash not simple concat

* Address comments:

- Range change in parent_hashes computation
- Slot not beind module Cycles anymore
- justified_slot part of the hash

Not addressed: using parent.slot_number instead of block.slot_number
