Derive IsList instances for EnumSet and EnumMap

[0xd34df00d]

This is an IMO handy usability enhancement, and it also makes EnumSet/EnumMap more of a drop-in replacement for IntSet/IntMap/HashSet/HashMap, all of which have an IsList instance.

Achievement unlocked: fail all CI jobs!

On a more serious note, it fails with

/usr/bin/docker exec  b2eb26cb4f33171f79399806f746b34cab8db705398a8ffa873ef92b5b68f9a7 sh -c "cat /etc/*release | grep ^ID"
/__e/node20/bin/node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /__e/node20/bin/node)

so it's unlikely to be related to my changes.

Huh, I see a very old haskell-ci (https://github.com/Mikolaj/enummapset/blob/master/.github/workflows/haskell-ci.yml#L11C12-L11C25), so no wonder it fails. Somebody needs to regenerate the script using a new haskell-ci version.

[Mikolaj]

I've regenerated the CI. Could you try rebasing on master?

[0xd34df00d]

@Mikolaj done! Thanks for taking a look into this — the CI actually caught some issues with the earlier GHC versions that I've fixed.

[Mikolaj]

LGTM. Shall we merge?

[0xd34df00d]

Yep, all clear on my side to merge!

While we're at it, could you please make and upload a new version of the package too, so I could depend on it in my code? Thanks!

[Mikolaj]

Shall that be 0.7.3.0 or 0.8.1.0? Does your change break PvP?

[Mikolaj]

I guess this a benign/almost external extension of the API, so let's stick with a minor bump: https://hackage.haskell.org/package/enummapset-0.7.3.0

[Mikolaj]

@0xd34df00d: thank you for the valuable contribution!

[0xd34df00d]

Thank you for merging and releasing!

This could break some existing code if it defines its own IsList instance for EnumMap or EnumSet, but that'll be an orphan instance, and those are generally "you know what you're signing up for" kind of thing IMO. So, a minor bump is good.
