Add more tests

[dapplion]

Motivation

In preparation for #197 it's important to increase test coverage to ensure stability

Description

Increase coverage in ssz with

• More tests by type testing serdes in struct + tree, clone, equal, and merkelization
• Copy the entire types from Lodestar and add script to do that in one command
• Add merge ssz_static tests
