V8 Coverage to Istanbul Coverage

v8 coverage + source map => raw code coverage

v8-to-istanbul convert --pattern "test-results/**/v8-coverage.json" --filters "{xxx.min.js}" --output ./ --merge --use-local

difference with https://github.com/istanbuljs/v8-to-istanbul

• coverage for all code in source map (not only code in v8 coverage)
• better performance (perhaps?)
