We should have a section explaining what a reconstructed state looks like and why.

feat(l2): commit blocks in batches (#2397)
a8d2ec4 
**Motivation**

To reduce the number of times we go to the L1 to commit/verify blocks.

**Description**

- Modifies `l1_committer` to merge as many blocks as possible into a
single `StateDiff` before committing, limited by the blob size.
- Modifies `StateDiff` to now contain both the resulting
`AccountUpdates` from executing all blocks in the batch and the header
of the last block.
- Adapts contracts to use `batchNumbers` instead of `blockNumbers`.
- Adds a new RPC endpoint, `ethrex_getWithdrawalProof`, which returns
all necessary data to claim an L1 withdrawal for a given L2 withdrawal
transaction hash.
- Implements `apply_account_updates` for the `ExecutionDB` to prepare
the db for executing the next block in the batch.
- Adds a `L2/storage` with the following tables:
- `block_number` => `batch_number`: Maps block numbers to batches (used
by the endpoint to locate a withdrawal's batch).
- `batch_number` => `Vec<block_number>`: Lists all block numbers
included in a given batch.
- `batch_number` => `withdrawal_hashes`: Stores withdrawal hashes per
batch (used to construct merkle proofs).
