Title: Support for minimal coverage and maximal coverage drop

Here is a proposal to implement two new features:
- return non-zero if the coverage is below a defined threshold (`min_coverage`)
- return non-zero if the coverage has dropped by more than a defined threshold since the last build (`max_coverage_difference`)

Please let me know if you're happy with this so I would add some explanations in the README.

Also, I extracted the JSON handling to a separate file to avoid code duplication between `result_merger.rb` and `last_run.rb`.

Thanks for this neat Gem :).
