Valeriy V. Vorotyntsev 0722d456fa chore: revamp coverage.sh
- Generate coverage report in JSON format --- it used to be a raw text
  file (non-JSON) with `.json` extension.
- Parse JSON data with Python instead of counting and `cut`ting fields.
  The resulting code is more readable.
- Allow specifying of coverage thresholds via environment variables.
- Generate HTML report and open it in the default browser with
  `./coverage.sh html`.
- Implement CLI.
