Add a column containing text report

[IndrajeetPatil]

Something like this but as a column adjacent to expression column:
https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/ggbetweenstats.html#reporting-1

Need to think how this is going to compare with https://easystats.github.io/report/

The difference is that report works with model objects, while statsExpressions does not. So maybe the functionalities should not overlap.

Will need to fix #1 first.

Need to convert the language expression to LaTeX equation.
