FR: Multi column limit the max number of columns in the settings

[g-adel]

It would be quite nice if there was a setting for the max number of columns in the [!multi-column]. The min width for callouts is quite nice, but the problem is that the layout can completely change depending on the current note width. Another possibility would be to allow to set the number of columns right next to [multi-column] with a modifier with pipe symbol. Thanks again for the awesome plugin.
