Changes (in) Coverage Check Action

This action will use your testing coverage report JSON to check coverage on changes made in on a branch and automatically find lines which are not present in the coverage report (this means probablly that it's not covered with a test). A markdown file with the results will be generated so this can be used (with for ex. sticky-pull-request-comment to post an PR comment). Tested with Vitest (c8) coverage report (full report, so not the summary)
