Pass point size as an array

[gerritholl]

Currently, ContourWriterBase.add_points takes for the point size a scalar value — all points are drawn with the same size.

pycoast/pycoast/cw_base.py

Lines 786 to 799 in 293f4da

	def add_points(
	self,
	image,
	area_def,
	points_list,
	font_file,
	font_size=12,
	symbol="circle",
	ptsize=6,
	outline="black",
	fill="white",
	coord_ref="lonlat",
	**kwargs,
	):

I would like to draw different points with different sizes, as one would do in matplotlib using scatter:

Is calling add_points multiple times an option?
