Useability Improvement -- Increase gradation on severity level display

name: Increase gradation on severity level display
about: Improve useability by adding more emphasis to more severity levels in table and html reports

Is your feature request related to a problem? Please describe

Currently only Critical and High vulnerabilities receive emphasis in the table and html reports. This could be slightly confusing/misleading to users as these lower severity entries are the same color as Info, None, etc. The main point here is that anything above Low reasonably needs addressed and should be emphasized in the reports to ease interpretation for users.

Describe the solution you'd like

I would like to see emphasis placed on Critical, High, Medium, and Low vulnerabilities in the table and html reports. This can take many different forms. One idea was to add more colors (ranging from yellow to red) to cover more levels. Another thought was to add icons based on the severity level.

Also could be nice to have a summary count at the top of both the table and html reports to further highlight and ease user experience.

A first pass was attempted to show what this could look like and should serve as a good starting point for this issue if/when it is worked. Link -- https://gitlab.com/hoppr/hoppr-cop/-/tree/more-sev-levels?ref_type=heads

Describe alternatives you've considered

This could be left as is and it is really just a minor usability improvement. I do think it is worth changing and should not take a huge amount of effort but will improve the experience for the users.
