Change mypy configuration to not ignore all missing imports

[codingpaula]

This PR edits the mypy config in the pyproject.toml to not ignore all missing imports. Instead it specifies the modules that don't have type annotations and need to be ignored.
It also fixes some minor things, mypy was complaining about:

• the @analysis.track in the driver.py wasn't properly recognized because the file and the instance of Track were called the same
• the usb_device.py uses the VideoWriter.fourcc function instead of VideoWriter__fourcc (as explained here: VideoWriter_fourcc doesn't exist in type stubs opencv/opencv#24818)
• the hardware_proxy.py was removed, since it's not used and wouldn't work correctly in it's current form
