ENH: Adding highlighting options to `to_latex` function
Following #3196, it would be extremely useful to add the possibility of highlighting the best value in a row or column of a DataFrame object when converting into a latex table (the `to_latex` function)

A convenient api for that would be to add a parameter to the `to_latex()` function, such as `highlight_rows=TYPE`, where TYPE can be `bold|italics|...` and than each row's best value would be highlighted.

There could also be a scenario where the best value is the lowest one, so maybe an additional parameter should be `best_highlight: str` between `high|low`.
