Integration with HUnit

[hyperswine]

I was interested in rust-analyzer's integration with cargo test and how quick you can simply write up a unit test and press run test above the function to run that specific test. Elm also has something similar which gives you a green tick next to test passes and red crosses next to failures. I think it would be interesting for hls to have something similar.

Also, maybe a way to run functions directly with a run function prompt above each function could also allow quick testing of quick inputs in addition to comments with evaluations

I've made good progress here: haskellfoundation/tech-proposals#46

The major things left to do are related to integration with HIE bios so that I get info about available test components and to monitor altered files...

thats really cool. It seems like you have something thats working pretty well already

I'm definitely interested in any pointers btw wrt hie-bios and also whether such a plugin would work well as part of the haskell VSC extensions
