These scripts can be used to set up a
local development environment to test
out sending transactions against

If the `DEVELOPMENT` env var is set, then
the initial genesis state will include funds
for the signer address. This prevents the
need to deposit funds or manually edit the
genesis json file.

fix

Add in the berlin precompile maps. This code is adopted from
upstream.

This includes the implementation of EIP-2565 which
makes the modular exponentiation precompile found
at `address(5)` cheaper.

https://eips.ethereum.org/EIPS/eip-2565

The berlin precompile set includes setting the `eip2565`
field to true on the `bigExpMod` struct.

This implementation is directly taken from upstream.

bss: split up SubmitBatchTx method in Driver iface

Previously it was being logged every time we modified the gas price.
Additionally, we log the raw byte length rather than tx.Size(). The
latter returns a float value of type StorageSize, which explains why the
metrics haven't been indicating actual byte values.

The current interface supports only one method for both crafting and
publishing a batch transaction, SubmitBatchTx. Currently this is being
executed on each new gas price that the txmgr commands, implying we are
doing a lot of extra work to rederive batches. In addition, much our
instrumentation lives inside this method, meaning that the they are also
being recorded multiple times per transaction. When we get to
processing larger batches on Kovan and Mainnet, this could also become a
resource bottleneck.

This commit remedies all of the above issues by splitting out the
transaction crafting process from the publication. A new method,
CraftBatchTx, is added to the Driver interface. This method is
responsible for creating a fully formed transaction, but does not
publish it. The responsibility of SubmitBatchTx is now modified to take
an predefined transaction, i.e. created by CraftBatchTx, overwrite the
supplied gas price, and publish. In this way, this expensive call to
build batches can be done once before handing the transaction of the
txmgr.

fix(batch-submitter): clear state root batches

Fixes a bug where both the sequencer and proposer main loops were
attempting to clear the pending transactions from the batch-tx
submitter's wallet. The impact is that we may have been overspending on
fees due to conflicting/reverting state batches. However the impact
overall should be minor given the relative size of state batches in
comparison to tx-batches.
