Automatic printing of indices

[gnopik]

Would be great if the computed indices were printed automatically when simdec.sensitivity_indices is run.

Now it requires several more lines:

foe = pd.Series(res.first_order.ravel(), index=X.columns, name="First-order effects")
display(foe.to_frame())

soe = np.asarray(res.second_order).ravel()
soe_matrix = soe.reshape(X.shape[1],X.shape[1])
cols = list(X.columns)
soe_df = pd.DataFrame(soe_matrix, index=cols, columns=cols)
display(soe_df)

si = pd.Series(np.asarray(res.si).ravel(), index=X.columns, name="Combined_indices")
si_with_total = si.to_frame()
si_with_total.loc["Total explained variance"] = si.sum()
display(si_with_total)

The aggregate table can have the following structure:

This code sample can be another function but I would keep a function that only does the calculations. If someone wants to use this in an optimization or else they will not want to get any printing. Also for maintenance and separation of concerns it's better. We can still have higher lever functions that do a full workflow.

As discussed today with @tupui and @justushelo , let's make an optional argument for displaying the indices.
