allow models to accept arguments at initialisation

[quantumjot]

We should pass arguments to models when they are loaded:

scivision/scivision/io/autoplumber.py

Lines 33 to 35 in 001a8f8

	# we could instantiate the model using the args here
	# args = config["args"]
	self._model = model()

I'm linking this PR in the test plugin repo, which has some discussion about arguments to an ImageNet model
