Simplify or downgrade id function

[meowsbits]

Is your feature request related to a problem? Please describe.

re: name -> hash as an identifier scheme. OpenSSL only began support for SHA3 in 2018-09. There are no security reasons for the hashing pattern, we just need unique IDs. Also SHA3-512 is kind of slow.

I think we should try to make the process of getting an id and the id itself as simple as possible.

Note also that since we'd be using a tiny substring of the hash, there's really no point in the extra bits (512 is overkill).

Describe the solution you'd like

• Use MD5. It gives a very reasonable enough chance of non-collisions. SHA1 would work fine too.

Describe alternatives you've considered

• id = "Just pick any noun that isn't taken or make up a word".
