ExtensionNotImplemented error

[gtgrp-user]

As suggested in a comment in #182, I tried the label collection in Africa (ref_landcovernet_af_v1_labels). However, I now receive the following error.

Thanks for looking into this, I haven't had a chance yet.

If you're interested in working on this, I suspect that this collection has started using the classification extension rather than the label extension. The notebook code will need to be updated as well.

Thanks for your quick response. I am using the pystac version 1.4.0 which doesn't include the classification extension. Am I missing something?

Closing this in favor of #182
