Build errors with recent GHC versions

[jhrcek]

Hello @sras

I'm pretty excited to have found this package.
I like the ergonomics and simplicity (yet very comprehensive support for aeson Options + out of the box support for parametrized types).

Are you still interested in maintaining this package?
I'm getting build errors when trying to build it with ghc 9.12.2.

I fixed this errors in my fork, replaced stack + package.yaml + travis config with plain cabal file and github actions CI config generated by haskell-ci, to make sure it builds with couple of recent GHC versions - see my fork where I made everything compile with ghc 9.6 - 9.12: https://github.com/jhrcek/elminator/pull/1/changes

I suspect those changes might be too large for your taste, so I'd like to check with you if you would be OK with (at least some of) the following changes from the above PR in my fork?:

1. fix ghc build errors

2. remove travis.yaml
3. add haskell-ci generated github actions config
4. fix hlint warnings
5. (optional) replace stack configs with cabal file (these days stack maintenance is on back burner and cabal is the more actively maintained buidl tool)
