Have manually triggered the doctests CI for this branch (which has rioxarray installed) at https://github.com/GenericMappingTools/pygmt/actions/runs/9867651036/job/27248357251, looks ok, but a couple of suggestions.

To be honest, we probably don't need the if hasattr(raster, "rio") check, because the spatial_ref int64 ... 0 line above (added in #3321) already means that rioxarray is used (the doctests CI run with rioxarray installed). But I guess it'll be good to mention rioxarray somewhere in the docstring, albeit indirectly.

Description of proposed changes
The
rioaccessor is only registered when rioxarray is imported. Currently, we import rioxarray inFigure.tilemap(pygmt/pygmt/src/tilemap.py
Line 12 in 3a32169
load_tile_map. Thus, the raster returned byload_tile_mapalone may have CRS set or not, depending on if a script importsrioxarrayor not elsewhere.This PR fixes the issue by importing the rioxarray package in
pygmt/datasets/tile_map.pyso that therioaccessor is always registered when rioxarray is installed.
