[Feature Request] Add additional stats to print

[lucasmation]

I just learned about this package and I am finding it super useful. Thank you.

A small suggestion: It would be great if the user could report other statistics to be used in descr. In my case, I am dealing with particularly skewed data so it would be interesting to be able to request other statistics such as percentile (90th percentile for instance).

Thanks for your feedback and suggestion. Will take it into consideration for a further release.

Haven't found a way to do it yet... I did however find a way to include custom statistics in dfSummary(). This document explains how: https://htmlpreview.github.io/?https://github.com/dcomtois/summarytools/blob/master/doc/Custom-Statistics-in-dfSummary.html
