Windows support

[aviaviavi]

Please indicate any desire for Windows support here. I can't take care of this now (don't have a Windows machine) but can prioritize if there is interest in using it.

If you're up for implementing this, I am happy to help.

I made a Windows build of curl-runnings using GitHub actions a few days ago. It uses choco to install stack and caches the STACK_ROOT so it doesn't have to recompile all the dependencies each time.

It need a bit of refinement (it currently publishes the whole install directory for example). It's possible to trigger a release from a github action too.

Here's an example build that publishes the exe:

Here's the workflow file:

@aviaviavi I'd like a Windows build so I'm happy to polish this POC if you think it's OK. It might be worth migrating the whole build/release system to github actions?

@paulcadman that would be excellent! I wrote the Travis build before GitHub Actions existed, having it in there definitely makes sense. If we merge your windows build, I can migrate the linux+osx build too.
