Add a way to write the PR comments in a compact manner using a markdown table

[SeeringPhil]

Is your feature request related to a problem? Please describe.
When running on multiple urls (in my case, a baseUrl with subPaths), the format is not as expected when displaying performance.
See issue #122

I think adding a way to display the results in a more compact manner, like the solution described below, would both provide a nice solution to my personal problem while adding a valuable new feature to everyone using the action.

Right now, the way the results are displayed quickly becomes noisy and clutters the PR, while having this possibility would improve the readability.

Describe the solution you'd like
Provide a mechanism to have a compact comment mode which would output something like this:

Device	URL	Accessibility	Best practices	Performance	PWA	SEO
mobile	baseUrl	95	90	95	80	100
desktop	baseUrl	90	90	95	80	100
mobile	baseUrl/subPath1	92	90	95	80	100
desktop	baseUrl/subPath1	92	90	95	80	100

Additional context
N/A

A suggestion for the possible input parameter could be :
'prCommentCompact'
or maybe
'prCommentTable'

@adamhenson Thanks for the feedback!

Knowing you accept PRs I'll take a look at implementing the changes I mentioned in those 2 issues when I'll get around to implement lighthouse checks in our projects.

Thanks @SeeringPhil - and FWIW this GitHub Action is pretty much a pass-through to @foo-software/lighthouse-check (which I also maintain), which is where the change would really need to happen.
