Append screenshots only on falied tests

[irapths]

Is your feature request related to a problem? Please describe.

We use cypress-mochawesome-reporter to generate report with videos (using the videoOnFailOnly parameter). Moreover we append execution info and logs (generated by cypress-terminal-report) as custom test context to failed tests.
Because of the large number of tests we rely on the "additional test context icon" on the right side of the report line, next to execution time, to check for failed tests. (Yes there is the filter button but then you miss the context of the test suite and is not very convenient for us in all cases)

Lately, we are starting to implement visual tests (using cypress-visual-regression). In order for the verifications to work screenshots are taken.
Screenshots are appended to each test in report without any effort, thanks to your great work :) , to any test that has one.

Unfortunately, and because of the visual tests, all the tests have at least one screenshot witch results to the "additional test context icon" to be placed to all of them.

Describe the solution you'd like

A way to enable/allow the addition of screenshots only on failed tests, like the videoOnFailOnly parameter (#141).
