fix(core): test hive genesis parsing #2145

Motivation

Hive tests require parsing many different geth genesis.jsons. This adds tests for deserializing many of the genesis files contained in the hive test suite, revealing that we don't correctly parse all of them.

TODO:

  • fix the genesis deserialization so that these tests pass

Solution

Use serde(default) for all required genesis fields, and add genesis test fields from geth to Genesis.

Support both hex and decimal decoding for GenesisAlloc fields.

PR Checklist

  • Added Tests
  • Added Documentation

I would consider putting this in a hive: HiveParams w/ serde(flatten) but we can leave for follow-up, we don't use the genesis type in other places either way
