Show file coverage in status bar

[alangordon]

I get a bit frustrated when I cannot easily see the coverage % of a specific file when that file is open in VS Code.

I would like an area beside the "Watch/Remove Watch" button in the status bar to show this. I'm not sure of any particular metric that would be best - but an option to have a few or either would be great. Lines, functions, branches etc

This is something I could work on if it is deemed suitable and possible.

It could go here:

@alangordon thanks for submitting a feature request! This is kinda similar to #151 but we might need to wait until microsoft/vscode#54938 is done before we could do this in the folder system.
If we go with your idea, the trickiest part will be making the status bar remove / watch more dynamic so it can also show coverage information, currently it simply toggles based on the state of the coverage system...
