Feature Request: serialize and deserialize hash result

[trim21]

I'm trying to hash some videos and save them to DB. Then check aganist to a new video.

I hope there can be a Hash object as video hash, can he serialize/deserialize to/from string or bytes, instead of current VideoHash, which can be only calculated from video source.

This isn't a terrible idea, although you can also directly compare the hashes as a hex or decimal instead, which is what I do.
