Cast Polygon to Multipolygon with ArchGDAL.jl

General Usage

I have a Vector{IGeometry{wkbMultiPolygon}} which I need to simplify for plotting.
However, doing ArchGDAL.simplify.(geoms, 0.001) results in some wkbMultiPolygons becoming wkbPolygons and Makie is not happy about the heterogeneous eltype of the container. Can I somehow cast the simple Polygons to MultiPolygons? Or is there a generally better way to do this?

I believe you can use ArchGDAL.forceto to convert to multi polygon.
