StateAtNextBlock is a helper function that returns the state at the next block. It wraps StateAtBlock and handles the case where Upgrades are applied to the next block. This is different than using StateAtBlock with [nextBlock] because it will apply the upgrades to the [parent] state before returning it.

type StorageRangeResult struct {
	Storage storageMap   `json:"storage"`
	NextKey *common.Hash `json:"nextKey"` // nil if Storage includes the last key in the trie.
}

StorageRangeResult is the result of a debug_storageRangeAt API call.
