EEZ Flow LVGL: roller and dropdown list as expression or input

[fietser28]

I would like to have the possibility to dynamically set the list of options in a roller and dropdown widget, just like in other options.
An expression should probably result in an an array of Strings.

Done. If expression is used then it expects an array of strings. Also, you must update to the latest version of eez-framework.
