Option to print the compiler versions in a shell-friendly format ?

[mmhat]

Currently get-tested outputs JSON:

$ get-tested my-project.cabal
["9.8.2", "9.10.1"]

It was nice if there was an option to print that in a more shell-friendly format, i.e. one version per line, unquoted:

$ get-tested --format=shell my-project.cabal
9.8.2
9.10.1

Then one could do something like for v in $(get-tested --shell); do cabal test all --with-compiler "ghc-${v}"; done...

Yes good idea, this would also lay the foundations for a --format=nix that was asked in #14.
