Module for interacting with ghci

[mrcjkb]

• Detect file type
• Detect build tool (cabal | stack | fallback to ghci)
• Send files, lines, selection, text objects, ... to repl

Possible alternative: iron.nvim
Does not seem flexible enough as a standalone, but it may be feasible to interface with it by setting repl_definition.haskell.command (?)

TODO: Handle ambiguous targets:

e.g.,

Error: cabal: Abmiguous target: 'lib/test/Spec.hs`.
It could be:
subpackage1-spec:test/Spec (file)
subpackage2-test:test/Spec (file)

Strategies:

• Simple built-in split
• toggleterm
• iron.nvim - if feat: allow to build the repl command using a lua function Vigemus/iron.nvim#300 gets merged
