Get and Set MP3 Tags with PowerShell and .NET DLLs

[SpriggsySpriggs]

I searched the internet and found code for getting and setting MP3 tags using PowerShell so I decided to adapt it for QB64 using my pipecom library. It uses a .NET DLL for PowerShell for getting tags and the PowerShell module for setting. You will need to download and install the PowerShell module here and install it by downloading the zip and extracting it to the modules folder. One could automate an install of this module at runtime if desired. More tags can be set than the ones I have provided but if someone wanted to they could expand this out.
