Fixed crash when passing string bins to histogram

Fix crash when passing string bins to histogram, to be consistent with the documentation: "If bins is a string, it defines the method used to calculate the optimal bin width, as defined by histogram_bin_edges.".

Hi @verdimrc ,

thanks for submitting this fix. I had a look at the MR and it looks fine for me. The tests did not pass, but this seems to be an issue with an old dependency in the pipeline, which I am currently fixing. I would directly merge the branch if this fits for you?

Best Patrik
