This extension shows native V8 code coverage in VSCode

Requirements: this extension works with monocart-coverage-reports

Install monocart-coverage-reports and generate coverage-report.json file with v8-json report.

const coverageOptions = {
    // ...
    reports: ['v8-json']
    // ...
}

Test with TypeScript project, open the file checker.ts (52K+ lines)

VSCode officially supports coverage view for the test runner, see test-coverage, I've tried adding V8 coverage data for the test runner, but it didn't luck. Maybe someone can help.
