Support for case when root project dir is parent of the Stack project

My current project structure is that there are many services, some shared libs and more, like this

• project root
  • build
  • docker
  • data
  • e2e
  • logs
  • modules
    • module_a (Java/Maven)
    • module_b (Kotlin/Gradle)
    • module_c (NodeJS/NPM)
    • module_d (Haskell/Stack)
    • module_e (Haskell/Stack)
    • and more

Actually there are like 50 microservices and I would like to test-drive Haskell.

As of now, I cannot open project root, navigate to Haskell/Stack project; Haskero works only when "module_d" is opened as a project root.

When I navigate to root/modules/module_d/src/Lib.hs, Haskero figures out the stack.yaml at modules/module_d and use it.
