Add html report as an output format

[coderpatros]

Is this an option that you would like added @tonerdo? I'd be happy to do some work in this space. I quite like the reports generated by coverage-viewer. It is written in node.js so it would need to be ported over to avoid the node.js dependency.

Edit: And I just double checked the licence for coverage-viewer and it is MIT as well.

@patros - I've done some work to ReportGenerator (danielpalme/ReportGenerator#130) that would make this feature a stones throw away if/when it gets merged and pushed up to NuGet. All it would involve is including a new package reference and a little bit of code to the CoverageResultTask. I've already got it hooked up in a custom build.

The advantage would be that coverlet wouldn't have to maintain the HTML report generation, but could simply update the package when new features are available.

@hunterjm good point about having to maintain the html report generation. With a few good options maintained outside of this project the next question is whether Toni wants to include human readable output formats or to let the user choose their html generator of choice.

@patros I'm currently leaning towards letting the user choose their html generator of choice. But definitely something to think about

@tonerdo I'll close this issue. It can always be reopened if you start to lean the other way.
