[New Functionality] "inspect_num()" add parameter to define number of columns.

Hello,

Firstly, thanks for your excellent and very handy package. I use it in my normal modeling flow and when I teach, I highlight it as the de-facto solution for automatic EDA.

When using it in rMarkdown reports, the charts for the numerical variables histograms get very small.

I think, it would get a lot better if it could be parametrized the number of columns for the charts, intead of maximizing the plotting area, extending the output long wise would make the charts bigger and more readable.

Thanks again, Carlos.
