Trees in audit details #990

User story

Reporting uncovered lines/branches/functions as individual issues in the coverage plugin isn't very consumer-friendly (too verbose) and has a big impact on data storage size. A more compact and understandable output format would be welcome. A table would be an option for coverage, although an expandable file tree would be even more convenient. This tree format would be applicable to some Lighthouse audit outputs as well.
