`classification_dataset_names` contains datasets that are deprecated, and misses datasets that are not

Hi,

When following the docs and iterating over `(classification_|regression_)dataset_names`, I noticed that some of the datasets were marked deprecated (#188 #185) but are still included in the list of datasets.

On the other hand, the new datasets that replaced the deprecated ones (#167 ) are missing in those lists.

Do you plan to keep the lists the way they are (to match the paper) or do you plan to update the lists (or even update the paper)?

I can help updating if you want.
