Import and plot raster data

In this exercise, we are going to use a raster dataset of the vegetation types map (available from https://www.wri.org). The raster values take a set of discrete values indicating the type of vegetation. Let's start with reading the data and plotting it together with the mining site data.

The mining sites dataset (mining_sites) is already loaded, and GeoPandas and matplotlib are already imported.
