New expression functions have been added that support the management of coordinate reference systems, namely:

• crs_from_text: Creates a coordinate reference system from a string definition. The string definition can be represented using a CRS code in auth:id format, a WKT definition, or a PROJ string definition of the CRS.
• crs_to_authid: Returns the identifier string for a coordinate reference system in the format authority:id, e.g., EPSG:4326.
