Add support for Go/Golang coverage reports

Is your feature request related to a problem? Please describe. Go/Golang coverage reports do not seem directly supported by this extension.

Describe the solution you’d like It would be awesome if the extension could understand the report generated by go test, out of the box.

Describe alternatives you’ve considered I tested another extension that was supposed to display the coverage of .go files, but it failed with an error message at startup.

Additional context Here’s a workaround that I used successfully to make Vscode Coverage Gutters display the coverage of my go files, run the following command:

$ go test -v -coverprofile=go-coverage.out -covermode=atomic -coverpkg=./... ./... && go run github.com/richardlt/gocover-cobertura < go-coverage.out > coverage.xml

… then, re-activate the “watch” if necessary. You should get something like that:

I have https://facebook.github.io/watchman/ configured to convert the go coverage to lcov format using https://github.com/jandelgado/gcov2lcov

[
    "trigger",
    ".",
    {
        "name": "coverage",
        "expression": [
            "anyof",
            [
                "match",
                "go-nmea.coverprofile",
                "wholename"
            ]
        ],
        "command": [
            "/home/munnik/go/bin/gcov2lcov",
            "-infile=go-nmea.coverprofile",
            "-outfile=lcov.info"
        ]
    }
]

This works great and the go-nmea.coverprofile file gets update the lcov.info is updated immediately.
