Add WofE CLI functions

[msorvoja]

This PR adds CLI functions for the two WofE functions.

In the first CLI function (weights_of_evidence_calculate_weights_cli), the resulting dataframe is saved into a CSV file and the arrays are saved as rasters. The number of deposit pixels and evidence pixels are only printed to the user.

In the second CLI function (weights_of_evidence_calculate_responses_cli), the resulting probability and confidence arrays are saved as rasters.

In the latter CLI function, there are at least two options how to transform the input rasters into an array of dictionaries needed in the corresponding toolkit function:

• Create dictionaries based on the number of input rasters and assign key-array pairs so that each dictionary has got the same keys, for example W+ and S_W+ (remove any uncommon keys), or
• read rasters into dictionaries based on their file path. This assumes that each set of outputs of weights_of_evidence_calculate_weights_cli are in separate folders. As many dictionaries will be created as there are distinct (innermost) folders in the paths of the input rasters. I'm not sure whether this approach will work with the plugin.

I believe the first approach makes more sense, but I'll let you comment which approach you prefer @nmaarnio.

In addition to my comments below, please add CLI function for agterberg_cheng_CI_test tool

@nmaarnio Ready for another review!

I think it looks good now and seems to work. I would only change the output file naming logic, see my comment below
