* Refactor simpleAbiEncode

* Revert unnecessary changes

* Remove comments

* Revert changes outside of this PR

* Revert changes outside of this PR

* Revert changes outside of this PR

* Fix broken tests

* Move OVM bytecode & ABI into constants

* Add crazy printlines

* Remove crazy comments

* Add a bunch of debug printlns

* Add helper fn for applying msgs to the EVM

* Limiting Geth to one transaction per block
* Adding TransitionBatchBuilder to build & submit rollup blocks

* Adding L1MessageSender to Transaction (#4)

* Adding L1MessageSender to Transaction
* Adding logic to omit L1MessageSender in encoding / decoding when nil and never use it in hash computation

Co-authored-by: ben-chain <ben@pseudonym.party>

* Fixing Geth Tests (#6)

Fixing broken tests, skipping tests we intentionally break, and configuring CI within Github Actions

* Hex Trie -> Binary Trie (#7)

*** Changing Hex Trie to Binary Trie ***

Note: This changes and/or comments out a bunch of tests, so if things break down the line, this is likely the cause!

* Ingest Block Batches (#8)

Handling BlockBatches in Geth at `SendBlockBatches` endpoint (eth_sendBlockBatches)

Other:
* Adding PR template
* Adding ability to set timestamp and making blocks use configured timestamp
* Adding ability to encode original tx nonce in calldata
* Adding L1MessageSender to Contract Creation Txs

* Add L1MessageSender to Message

* Increment nonce on CREATE failure

* Fix bug where evm.Time=0

* Use state dump with hardcoded EM & SM addrs

- ExecutionMgr address should always be 0x0000...dead0000
- StateMgr address should always be 0x0000...dead0001

* Move EM deployment into genesis block maker

* Update EM contracts to latest version

* Update EM to remove events

* Fix the OVM tests

* Skip an ungodly number of tests

* Fix lint errors

* Clean up logging

* Cleanup more logs

* Use local reference to state manager

* Rename applyOvmToState(..)

* Remove unneeded check

* Clean up logging & add EM ABI panic

* Add gas metering to SM & small refactor

* Update core/vm/state_manager.go
