Update to GHC >9.6.

[a-02]

I'm not certain how to ask these sort of questions, but I'd like to use this library for my work and would be glad to take over maintaining it.

I'm happy to accept help. If you send me PRs to keep up with GHC releases I'll respond promptly (review, merge, release or revise on Hackage as needed). For more substantial features I'll consider them case by case. I'm not ready to grant permissions just yet but we can discuss that after we get more familiar working together. Would that work for you?

[a-02]

Absolutely! I'll see about punching something up sometime this week.

Turns out everything builds and tests perfectly fine on 9.8.2 and 9.10.1. Hm.

[Lysxia]

It would be good to update the CI script to build with those versions.
