Area plot clean up

[JustinElms]

Background

This address three bugs in the area plotter and cleans up some inefficient code:

• Correctly removes lakes from the basemap layer so that inland datasets (e.g. WCPS) are visible in the plot.
• Correctly wraps bathymetry contours at edges of projection
• Fix plot size bounding logic to prevent edge case errors

Why did you take this approach?

The geometry splitting approach used previous doesn't seem to fix issues at the projection bounds and adds a lot of unnecessary code.

Anything in particular that should be highlighted?

There are still some edge cases where the orientation of area polygons crossing the dateline in all projections can get reversed. To prevent this it might be best to get the centroid from the feature in the UI map component and include it with the plot query.

Checks

• I ran unit tests.
• I've tested the relevant changes from a user POV.
• I've formatted my Python code using black ..
