Display coverage percentage next to files in the file explorer

[AlCalzone]

When opening a coverage report, e.g. from nyc, I first get an overview of coverage for files and folders. It would be nice to see this percentage next to the files in the file explorer (if that is even possible).

@AlCalzone thanks for submitting an issue. Other then the make your own tree view (https://github.com/Microsoft/vscode-extension-samples/tree/master/tree-view-sample) I do not know of a way to add to the existing file explorer, myself but I will ask the vscode dev slack group and see if anyone knows more 😄 .

@AlCalzone looked a little further and got some feedback from the slack channel, microsoft/vscode#54938 it is coming eventually so in the future something like the could be added 😄

For the ones who want to have a solution in the mean time, I've created an extension that adds a TreeView to the Test Explorer, it is pretty basic, and in experimental state (Not unit tested, not published...) but I'm using it within a Flutter project. I needed an easy way to visualise my coverage and navigate it.
Please be indulgent as it is my first extension and written as a draft.

@tenninebt thanks for bringing your extension up! looks cool for a first stab at extension building 😁.
I also need to convert this project to webpack eventually as well so it was good to see how you implemented that.

@ryanluker looks like the vscode issue you linked to has been resolved. Is it possible to look at this again?

[ryanluker]

@MalachiMackie Thanks for the ping! We can definitely take another look at implementing this for sure.

If it shows out that it still doesn't work by means of vscode, then integrating koverage tenninebt/vscode-koverage#24 may be a good solution.

Idea to use vscode.FileDecorationProvider:

• Vs code offers the ability to decorate the file tree explorer view with badges and colors
• Badge seems to allow two characters so we can show percentage rounded
• Color threshold can be set by the user in the extension settings

Nice! That would work well, thanks for the mockup too!
