Add support for AltCover

According to https://community.sonarsource.com/t/coverage-troubleshooting-guide-for-net-code-coverage-import/37151,

      We support the following code coverage tools:
      
      * Visual Studio Code Coverage
      * dotCover
      * OpenCover/Coverlet

However, OpenCover is depreciated (ref. https://github.com/OpenCover/opencover). Please add support for AltCover to replace OpenCover.

Hi Lindsay

Thanks for the suggestion we will consider it. Have you tried Coverlet? If so, do you see an advantage of AltCover over Coverlet?

Thanks

Tom

I did try to use Coverlet, and I couldn’t get it to integrate with SonarCloud. I had to switch to OpenCover to integrate.

Hi Lindsey

If you let me know the problems you encountered with Coverlet, I’d be happy to take a look and see if we can help. I appreciate setting up coverage isn’t always as easy as it should be.
