Add support for POST requests

Nobody has claimed this yet.

Now the XSSRadare works well, but can only discover XSS on GET parameters.
I'm trying to add handling for POST requests, but I haven't succeeded.

For example I have tried this library:

- [https://pypi.org/project/selenium-requests/](https://pypi.org/project/selenium-requests/)

As suggested in:

- [https://stackoverflow.com/questions/5660956/is-there-any-way-to-start-with-a-post-request-using-selenium](https://stackoverflow.com/questions/5660956/is-there-any-way-to-start-with-a-post-request-using-selenium)

But this doesn't work..

Have you ever tried to do this? If you know how, I can implement this for you and merge it. It would be very useful to handle POST request and not only GET.

Start by locating XSSRadare’s existing GET-parameter discovery flow and how it uses Selenium. Review the linked selenium-requests and Selenium POST-request references, then define a reproducible POST case and verify that the scanner discovers XSS through it. Done means POST requests are handled in addition to GET parameters.
