Check if suggested dependencies required to run the

}
\details{
Packages required to run the GUI (\strong{\code{shiny}}- and
\strong{\code{leaflet}}-related packages), which were \strong{\code{sen2r}} dependencies until
version 1.3.4, are now suggested dependencies.
\strong{\code{sen2r}} can be used without them with the exception of the GUI.
