Audited MiMC and SparseMerkleProof contracts

The release covers the audited and updated contracts for the MiMC hashing contract and the SparseMerkleProof contract audited by Diligence.

Gas optimizations on blob submission and TokenBridge

Change Log

The commit contains the following:

• Major gas optimizations for blob submission
• Some gas optimizations in finalization
• Gas optimizations in the TokenBridge

External Breaking Changes

• LineaRollup's DataSubmitted is replaced with DataSubmittedV2 - (using shnarf vs. dataHash)
• TokenBridge's BridgingInitiated is replaced with BridgingInitiatedV2 - (indexes recipient vs. amount)
• TokenBridge's BridgingFinalized is replaced with BridgingFinalizedV2 - (indexes recipient vs. amount)

Auditing

Additionally, the code included in the following commit has been audited by OpenZepplin and Cyfrin.
