IAU CRSs invalid projection (crs not found) from URLs, fine from URNs

[AndrewAnnex]

IAU CRS codes such as IAU_2015:49900 added in #2876 are available via IAU_2015:49900 and by urns like `'urn:ogc:def:crs:IAU:2015:49900' but URLs recently added by the OGC NA like https://www.opengis.net/def/crs/IAU/2015/49900 result in a proj_create: crs not found error in projects like pyproj.

I am using the latest release of pyproj (3.4.1) when I run into this error but I believe the error is internal to Proj.

Example of problem

import pyproj 
print(pyproj.__version__, pyproj.proj_version_str) # 3.4.1, 9.1.0 
pyproj.CRS('IAU_2015:49900') # passes
pyproj.CRS('urn:ogc:def:crs:IAU:2015:49900') # passes
pyproj.CRS('http://www.opengis.net/def/crs/IAU/2015/49900')  # fails 

exception:

File pyproj/_crs.pyx:2352, in pyproj._crs._CRS.__init__()

CRSError: Invalid projection: http://www.opengis.net/def/crs/IAU/2015/49900: (Internal Proj Error: proj_create: crs not found)

Problem description

URLs from the OGC NA for IAU projections should resolve just the same as the URNs. I am not sure how PROJ checks if a crs is valid, so maybe there is some internal database file to update?

Expected Output

no invalid projection errors

Environment Information

• PROJ version 9.1.0
• Operation System Information (macOS 13.1)

Installation method

• Python 3.10.8 using poetry to install things
