`engine_getPayloadBodiesByRangeV1` can fetch too many payload bodies
https://github.com/status-im/nimbus-eth1/blob/67b8dd7fdc8d1734ff6f8540e05ae1f66b37ab26/nimbus/beacon/api_handler/api_getbodies.nim#L63-L78
It calculates this `last` payload body to fetch but ultimately that doesn't matter, it fetches all of `start..ben.chain.baseNumber`, which could be arbitrarily more more than the `maxBodyRequest == 32` intended.
