Verified that this can be installed on a fresh windows install
Please see changes to Readme and environment.yaml file

Thanks, it's good to have an independent confirmation that this is working on Windows, and documentation of the minimal option for installing the Microsoft compiler.

Is there a reason for pinning this specific version of cxx-compiler?

Suggested change

	For windows computers make sure that you have installed build tools `C++ build tools <https://visualstudio.microsoft.com/visual-cpp-build-tools>`
	This must be installed manually
	For Windows computers, make sure that you have installed `Microsoft C++ Build Tools <https://visualstudio.microsoft.com/visual-cpp-build-tools>`_.
	This must be installed manually.

My pleasure, let me do a couple more tests with cxx-compiler as the docs suggest it's supposed to install the compiler which means it should make it easier for "fresh machines".
i.e. it should install g++ on Linux, Clang on Mac and VC on Windows.

I have a few versions of C++ build tools on my PC, the other PC also had a few, but it didn't play nice with 2022 build tools.
I will update the documentation and send some screenshots to this PR.

Just tested the install using the GitHub runners on a new branch on my fork. I created a few runners for each Python version and OS.

• For Ubuntu this works well, cxx-compiler installs g++; scons builds and installs everything no problem.

• For Mac, I had to make a tweak to get the runner working as the scons install as the platform version was looking for a wheel file for macos-10.9
  Would be keen to understand if other Mac users are experiencing similar issues.

• For Windows cxx-compiler seems to install msvc but I get path related errors when running scons build. This is not an issue on bare metal if 2019 build tools is installed.

I'll update the readme with some information on this.
