Changes Made

• Fix: LoadMaxBlockSize working inconsistently when creating and handling a sent block, now they both share the same behavior
• Fix: Check for empty order books on ProcessRootChainOrderBook which caused the orders to be checked even if no orders were sent
• Feat: Add transaction batch support
• Feat: LRU cache for public keys on FSM, this helps optimize consensus when a block contains multiple transactions with the same sender
• Feat: Allow for multiple transactions to be listened not processed in parallel.
• Change: Now using CommitCertificateParallel and smt.CommitParallel for consensus commit
