Tutorial showcasing Mars Orbiter Laser Altimeter (MOLA) dataset, focusing on Olympus Mons. Data loaded via `pygmt.datasets.load_mars_relief`, plotting in 2D with `grdimage`, and in 3D using `grdview`.

 data processing pipeline over Wellington, New Zealand. Doing data loading using laspy, pre-processing with `blockmedian`, gridding with `surface`, and plotting in 2D with `grdimage` and in 3D using `grdview`.

Include tut5_topography in Table of Contents, and citation for the MOLA dataset.

Draft section on plotting an Antarctic DEM with RGB image overlay. Using REMA as the DEM, and Sentinel-2 L2A imagery. Need to mosaic two tiles together using rioxarray for both the DEM and RGB imagery. Have done a quick `grdview` plot based on my old code at weiji14/30DayMapChallenge2021@61f5698.
