Description of proposed changes

Adds a gallery example showing how to reduce irregular bathymetry observations
with pygmt.blockmedian before interpolating them with pygmt.surface.

The example uses the built-in bathymetry sample dataset and compares the reduced
observations with the resulting grid.

Fixes #1352
