PROPOSAL: Use certify to set CURL_CA_BUNDLE

[snowman2]

https://pypi.org/project/certifi/

Example of what I am thinking:

import os

import certifi

os.environ.setdefault("CURL_CA_BUNDLE", certifi.where())

I think this will help with the transition to using GDAL 3 and PROJ 7 in the wheels.

@snowman2 this is useful right away! I'm going to do it.

Thanks @sgillies 👍

If you wait until GDAL 3.2 and PROJ 7.2 are released and include them in the wheels, you could instead set GDAL_CURL_CA_BUNDLE and PROJ_CURL_CA_BUNDLE.

The current implementation is great, this is just an idea bugging my brain:

I found that rasterio.Env(CURL_CA_BUNDLE=cacert.where()) and also worked for vsicurl. Another option could be to add CURL_CA_BUNDLE=cacert.where() to default_options and also set the PROJ_CURL_CA_BUNDLE environment variable.
