Rationale

It is possible to fetch a single storage slot of a contract using debug_getStorageAt method. Anyone doing local simulations will need to call this method over and over and concur the overhead of repeated calls.

The idea is to implement a new method, perhaps batchGetStorageAt which fetches multiple slots of the same contract or even batchGetStorage which can receive a mapping of contract addresses to slot keys and returns the relevant storages of those accounts.
