marker_z doesn't seem to be passed correctly in scatter plots of geometry

[evetion]

Might extend to many other geometries/attributes.

Plotting of points with a color doesn't seem to work.

using GeoInterface, ArchGDAL, Plots
geom = ArchGDAL.createpoint.(rand(10), rand(10))
plot(geom, seriestype=:scatter, marker_z=rand(10))

If we bypass our recipe however, we get colors

plot(Tuple.(GeoInterface.coordinates.(geom)), seriestype=:scatter, marker_z=rand(10))

Also note that a label is now automatically added.

Hmm, if I pass a label to the first plot, you get 10 labels, implicating our recipes is sending 10 series of a single(?) point to the backend.

edit: If you pass a matrix as colors, like marker_z=rand(1,10), you do end up with different colors.

Relates to JuliaPlots/Plots.jl#3880

Simple fix passing colors as an adjoint:
plot(geom, seriestype=:scatter, marker_z=rand(10)')
