upped scikit-image and some naming changes

[WillemSpek]

see #613 it's just some very minor changes that should enhance compatibility and not impede functionality. Should be a quick review :)

What exactly does this fix?

Thanks for the review!

1. Dependency conflict

ERROR: Cannot install -r requirements.in (line 3) and -r requirements.in (line 7) because these package versions have conflicting dependencies.

The conflict is caused by:
dianna 0.9.0 depends on scikit-image==0.19.1
quantus 0.4.0 depends on scikit-image>=0.19.3

2. problem with Quantus and DIANNA integration:

TypeError: explain() got multiple values for argument 'model'

Basically because quantus also uses model to pass on to the explain function which collides with the required positional argument model from DIANNA in kernelshap.explain. On top of that, model_or_function appears to be consistent with the naming for the other methods.
