Added new resources and improved interaction script and custom python endpoint

Changes in this PR

• I added some shared experiment resources (video, audio, different images, subtitles, font, PDF). I believe these could be useful for testing other security policies as well, so I left them in the main folder. However, if you prefer, we can move them to SOP subfolder.
• I added OPEN_CONSOLE command to the interaction script to open browser's JavaScript console.
• I added report_leak argument passed to the custom Python endpoint's main function which allows the user to report a leak from the server directly. So far, the only option was to return a redirect to the reporting endpoint, which would not work if the browser did not follow redirects for the request.

Unless anything else shows up, this should conclude my work on BugHog. I will polish the experiments and submit a PR adding them to the repo soon.
