Add powershell script for windows users

[NateBrady23]

I love what you did with Gitpod as this opens up contribution possibilities for a ton of people!

I'm a windows user with wsl disabled (for reasons) and like to develop locally or in a windows VM. This adds a PowerShell script to do the same as the existing bash script, sans the Gitpod functionality.

So far we are much success, but waiting on a few more tests (and lila compilation) to make sure everything is working as expected, so marking as draft.

Thanks for all your work on this project!

Thanks for your work on this! The structure of the repo has changed quite a bit so this would need to be updated.

Open to future PRs on this.
