Autodetect failed installation and recover from it

There are instances where csharpier is partially installed and if fails to run. This is the output from VSCode

["WARN" - 5:05:10 PM] Exception while running 'dotnet csharpier --version' in C:\Users\<WITHHELD>\AppData\Local\CSharpier\0.20.0
"Cannot use file stream for [C:\\Users\\<WITHHELD>\\AppData\\Local\\CSharpier\\0.20.0\\.store\\csharpier\\0.20.0\\csharpier\\0.20.0\\tools\\net6.0\\any\\dotnet-csharpier.deps.json]: No such file or directory\r\nA fatal error was encountered.

["ERROR" - 5:05:10 PM] ,,Tool 'csharpier' is already installed.

["DEBUG" - 5:05:10 PM] returning NullCSharpierProcess because of the previous error when trying to set up a csharpier process

The extensions install csharpier to a custom directory because they keep the dotnet tool running in the background. If they kept csharpier running from the default location then a user will run into issues if they run commands to update csharpier.

Testing the install can be done with the following command

C:\Users\[USER]\AppData\Local\CSharpier\[Version]\dotnet-csharpier --version`

Deleting that directory and restarting VSCode would get the extension to reinstall csharpier in the custom location.

It should be possible for the extensions to detect this and attempt to delete and reinstall csharpier.

I did this a while ago and forgot to close the issue
