Add datagrid() function?

[DominiqueMakowski]

One of the big missing features in the stats modelling Julia ecosystem includes marginal effects-related computations (emmeans and marginaleffects in R).

These mostly rely on a processing of model-predictions, which itself relies on the ability to generate datagrids. Datagrids are also very useful for model-based visualization.

I am interested in implementing such a method in Julia, and I think that this package would likely be the best place for it, as it's something fairly generic. What do you think?
