KeyValueBytesStoreSupplier is the extension of the StoreSupplier contract for store suppliers of KeyValueStores (of Bytes keys and byte[] values, i.e. StoreSupplier<KeyValueStore<Bytes, byte[]>>).

KeyValueBytesStoreSupplier offers no new methods and simply specifies the type of the StateStores to supply, i.e. KeyValueStore<Bytes, byte[]>.
