Genesis Block Does Not Match Parity

[ansermino]

We appear to be having issues getting Geth to produce the same genesis block as the Parity Aura implementation.

You can see the genesis block configurations here:
Parity: https://github.com/goerli/testnet/blob/master/parity/goerli.json
Geth:

go-ethereum-aura/params/config.go

Line 83 in 1743af1

GoerliChainConfig = &ChainConfig{

(Alternatively: https://github.com/goerli/testnet/blob/master/geth/goerli.genesis)

These are the genesis blocks retrieved via RPC:
https://gist.github.com/ansermino/f4e9a3ebaf7ad9a0f52da53e9bbb6b1d

We can log the RLP encoding in geth and should get this:

This can be decoded with rlpdump (make all && ./buid/bin/rlpdump -hex <encoded data>):

A similar dump from Parity would be very useful. The leading theory is that a disagreement in the signature field construction is causing this issue.
