Interaction heuristic arguments

[mayer79]

This PR adds arguments to potential_interactions() and sv_dependence() to control the interaction heuristic used to select color features.

Status:

• [x] Add argument nbins = NULL to potential_interactions()
• [x] Switch to R-squared adjusted
• [x] Add argument color_num = TRUE to potential_interactions()
• [x] Add argument scale to potential_interactions() that allows multiplication with SHAP variance
• [x] Add argument adjusted = FALSE
• [x] Add all new arguments to sv_dependence().
• [x] Update NEWS
• [x] Unit tests for potential_interactions()

This is a step towards https://github.com/ModelOriented/shapviz/issues/119
