Passed all tests I could fine in the repo. ;)

Thank you very much! I'm merging this but I need to (re)learn how to publish Purescript packages. So might take a little while to get this up on the registry

[benjamin-hodgson]

Did this but looks like it hasn't been picked up yet, I'll check back tomorrow maybe purescript/registry#302

I should also set up a CI workflow and some tests, probably

I think SemVer requires a MAJOR version change (so, v1.0.0 instead of v0.6.0), since some of the type class instances were "removed": their requirements/context changed, so they might not be available at some types where they were previously available. But, at this point, I don't see practical advantages to a version bump.

I guess that's true. Ah well. I think it's unlikely to matter, haha
