ENH: add dataframe render trimming in Styler to avoid browser crash

[attack68]

DataFrame.to_html has max rows and max cols to automatically trim the console or string output.

DataFrame.styler.render does not and with large DataFrames this can potentially crash the browser of a Jupyter Notebook, or maybe a console.

Personally, I use Styler occasionally to quickly avoid the reasonably small max values in the former and this I would want to keep, but some tolerable, larger limit should be imposed in my opinion.
