VS 2022 Support

[coryshaw1]

Request to support for the recently released Visual Studio 2022.

Migration to 2022: https://docs.microsoft.com/en-us/visualstudio/extensibility/migration/update-visual-studio-extension?view=vs-2022

I briefly tried to upgrade the solution myself, but I ran into getting anything to hit breakpoints other than with the options setters. I was able to successfully install onto 2022, but nothing is happening on updating any code within the opened project. Not sure if any of the listeners are even initializing. I don't see any CodeStats API calls going out through Wireshark/Fiddler. Take this with a grain of salt though, I have no extension development experience.

I don't really know what I'm doing either when it comes to extension dev, but I did get it to compile and work over at my fork (I see the posts getting sent via Fiddler): https://github.com/hcorion/CodeStats.Client/releases/tag/vs2022
I uploaded the .vsix, but if you don't trust random people on the internet feel free to compile it yourself from the master branch of my fork, it has all my changes. I updated a bunch of stuff to get it to compile and maybe broke things for older versions of Visual Studio, not really sure, so I don't really want to PR it.

Perhaps @mastorm would be willing to look at my changes (hcorion@58c69bf)?
