Add module fixes for dependents, and test utils (#24)
Patch for module conflict when used as a dependency: `github.com/ethereum/c-kzg-4844/bindings/go` was moved to become part of `github.com/ethereum/c-kzg-4844` by `v0.4.0`.

```

Also adds test utils from https://git.vdb.to/cerc-io/ipld-eth-db-validator to be shared by cerc-io/ipld-eth-statedb#5 and wherever else.
