ARC (https://github.com/algorandfoundation/ARCs) sometimes requires hashing of some messages. This change is to ensure that `arcXXXX` is reserved for that purpose. This change is already in the go-algorand code: https://github.com/algorand/go-algorand/blob/2bc55c06f4dacf247b93a15f47530f57b4925d28/protocol/hash.go#L28

I don't know that this needs to be in the algorand spec, proper. These hashes always appear above L1, don't they? |

It's mostly to be sure there is no collision of prefix between L1 and above levels. |
