GB.Meta() errors for Multi Geometries about geometrybasics.jl

[visr]

A key point here is that generally a multi geometry is interpreted similarly to a single geometry, i.e. one feature, or one row in a table.

It may be fine to have multi geometries implemented as vectors of their single part versions, but they are not the same thing. In a vector of points, each point can have it's own metadata. In a MultiPoint, there is only one geometry, so only one metadata. Having a single multi geometry as a StructArray therefore does not quite seem the right approach.

One possible workaround is the way this issue was solved #52, i.e. defining a meta type for remaining multigeometries,
but as @visr pointed out the meta() call is going here rather than going to the overload method, so there might be something else happening?
