rollup node experiments

Test scripts etc. for experimental rollup testing.

untested, work in progress

python -m venv venv
source venv/bin/activate

# generate a `l1_genesis.json` and `l2_genesis.json` for local L1 and L2 geth instances
python gen_confs.py

TODO:

• configure PoA in L1 local testnet:
  • configure PoA signers in chain config
  • set genesis extra-data to PoA signer pub

Then:

• setup L1 node with L1 chain config (geth init --todo), with upstream geth
• setup L2 engine with L2 chain config (geth init --todo), but with https://github.com/ethereum-optimism/reference-optimistic-geth optimism-prototype branch
• setup L2 rollup node (https://github.com/ethereum-optimism/optimistic-specs/)
