Polygon zkEVM API method that returns the batch number associated with a given block number in the zkEVM chain.

In the zkEVM chain, multiple transactions are grouped together and verified as a single batch using zero-knowledge proofs. At the time of writing, the Polygon zkEVM works such that all individual transactions of a particular batch are processed as a separate block so that multiple blocks can be associated with a single batch of transactions.
