Cross-section issue with crevasses

[mdtanker]

The gallery examples for the profile module appear to plot 'icebergs' where there may be basal crevassing. This is likely an issue with fillnans or create_profile's interpolation based on parameter num.

Occurs whether num is set or not.

This is an issue with all methods (shapefile, points, polyline).
