MAUCacheAdmin PowerShell Module

[nixtar]

Hey Paul,

Hope you are doing well.

I needed a powershell version of MAUCacheAdmin and I hacked together something that worked but wasn't pretty.

I randomly got some motivation to rewrite what I had done as a PS module, and this is the result.

If you are not interested in hosting the module in this repository, then I'm happy to maintain a dedicated MAUCacheAdminModule repository personally.

I've included a README.md that goes over it at a high level.

Please let me know your thoughts.
