FYI we fixed this in #61 by replacing the URI by urn:ogc:def:crs:EPSG:2193.

import rasterio
rasterio.crs.CRS.from_string("urn:ogc:def:crs:EPSG:2193") == rasterio.crs.CRS.from_user_input("https://www.opengis.net/def/crs/EPSG/0/2193")
>>> True

Well it should have been "urn:ogc:def:crs:EPSG::2193" not "urn:ogc:def:crs:EPSG:2193" 🤦

FYI it works with rasterio but not with pyproj

import pyproj
import rasterio

rasterio.crs.CRS.from_string("urn:ogc:def:crs:EPSG:2193")
>>> CRS.from_epsg(2193)

pyproj.CRS.from_user_input("urn:ogc:def:crs:EPSG:2193")
>>> CRSError: Invalid projection: urn:ogc:def:crs:EPSG:2193: (Internal Proj Error: proj_create: unrecognized format / unknown name)

rasterio.crs.CRS.from_string("urn:ogc:def:crs:EPSG::2193")
>>> CRS.from_epsg(2193)

pyproj.CRS.from_user_input("urn:ogc:def:crs:EPSG::2193")
>>>

Interesting, so GDAL only added support for https uris in 3.0, we do not use much (any?) gdal v2 any more so havent noticed this issue.

We took these from the OGC doc https://docs.opengeospatial.org/is/17-083r2/17-083r2.html when we imported the WebMercatorQuad TMS, then when making this TMS we just used that standard.
