This commit switches to an Hackage-released version of HSvm, specifically 0.1.1.3.22, which is the same we were previously relying on, but by pinning on a specific commit 3fe28b683aba5ddf05e3b5f8eced0bd05c5a29f9 of the GitHub repo.

I have done the due diligence to make sure the version we were previously using was the same of the released one, to avoid nasty regressions. In particular, I have compared the SHAs of all the files in the project, both for the Hackage version and the Github version (after checking out the correct commit SHA) and here are the results:

The TL;DR is that the Hackage version includes the same code as the version we were previously using.

Another stepping stone for #180.
