Add JUnit report support

[ken-duck]

A suggestion from @vveider from a different thread.

And how about JUnit reports? Without it using such plugin on CI/CD services is most impracticable.

Thanks, @ken-duck!
I'm writing converter right now (with the same format as OWASP provides).
If you do not mind, I'd like to paste a link here once it is ready until feature request is ready.

That sounds great. Thanks!

I'm new to Python (this is my first script on it ever), so please do not scold to much :)
Propositions and improvements are welcome.
