- see https://gitlab.haskell.org/haskell/ghcup-hs#configuration for a more in-depth explanation
* add a `--set` switch to `ghcup install ghc` to automatically set as default after install
* emit warnings when CC/LD is set wrt #82
* add support for version ranges in distro specifiers wrt #84
- e.g. `"(>= 19 && <= 20) || ==0.2.2"` is a valid version key for distro
