Obtain coordinate system metadata from various data formats. There are
functions to extract a 'CRS' (coordinate reference system,
<https://en.wikipedia.org/wiki/Spatial_reference_system>) in 'EPSG'
(European Petroleum Survey Group, <http://www.epsg.org/>), 'PROJ4'
<https://proj.org/>, or 'WKT2' (Well-Known Text 2,
<http://docs.opengeospatial.org/is/12-063r5/12-063r5.html>) forms.
This is purely for getting simple metadata from in-memory formats,
please use other tools for out of memory data sources.
