USB type C is not part of the specification, if this doesn't work there's not much that can be done about it.

monitor.get_input_source() fails if the current is an unlisted value, such as 27. I'm using DELL monitors on Windows.

Traceback (most recent call last):
  File "C:\Users\kojii\AppData\Local\Programs\Python\Python310\lib\site-packages\monitorcontrol\monitorcontrol.py", line 464, in get_input_source
    return InputSource(value)
  File "C:\Users\kojii\AppData\Local\Programs\Python\Python310\lib\enum.py", line 385, in __call__
    return cls.__new__(cls, value)
  File "C:\Users\kojii\AppData\Local\Programs\Python\Python310\lib\enum.py", line 710, in __new__
    raise ve_exc
ValueError: 27 is not a valid InputSource

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\src\bin\dpswitch.py", line 35, in <module>
    run()
  File "C:\src\bin\dpswitch.py", line 25, in run
    current_input = monitor.get_input_source()
  File "C:\Users\kojii\AppData\Local\Programs\Python\Python310\lib\site-packages\monitorcontrol\monitorcontrol.py", line 466, in get_input_source
    raise InputSourceValueError(f"{value} is not a valid InputSource", value)
monitorcontrol.monitorcontrol.InputSourceValueError: 27 is not a valid InputSource

I'm not sure if the specification allows such non-standard values, but great if it can return the raw value without errors.
