Support Python 3.14

Hello,

When I install this package with Python 3.14, there is an error

Traceback (most recent call last):
  File "/opt/homebrew/Cellar/onionprobe/1.4.0/bin/onionprobe", line 7, in <module>
    sys.exit(run_from_cmdline())

    action = action_class(**kwargs)
TypeError: BooleanOptionalAction.__init__() got an unexpected keyword argument 'type'

and so there should be some fix.

Can you take a look?

Thanks,
