Use contourpy directly #54

matplotlib uses an underlying python contouring library contourpy.

This is a much more suitable tool for implementing contouring in QGIS and provides a simpler contouring interface.

It is installed if matplotlib is installed, so will be available in any case if matplotlib is (ie not additional installation). But using it directly means that it can be used without the extra code of matplotlib.

Further investigated and it turns out that contourpy is purely for contouring data on a grid of x,y values. We would still need matplotlib (or something else) for contouring by triangulating irregular data. So not pursuing this further ATM.
