add additional info to .last_run.json

[cppgent0]

This is not a bug/issue. It is an enhancement request.

Currently the .last_run.json file only contains line and branch info.

The simplecov-html.output_message function prints other info:

Line Coverage: 85.23% (623 / 731)
Branch Coverage: 58.39% (87 / 149)

It would be great to also add these to the .last_run.json content:

• result.covered_lines
• result.total_lines
• result.covered_branches
• result.total_branches
