[Bug]: AWS SSO no longer supported as of v.1.2.0

[atzannes]

What happened?

t = DeltaTable('s3://bucket/prefix')

This used to work up to v 1.1.4 with my AWS SSO configuration but staring v1.2.0 I am getting this error

I posted the relevant logs below, but the key seems to be "This behavior requires following cargo feature(s) enabled: sso."

I looked at the pyproject.toml for release 1.2.1 and tried the extras (pandas & pyarrow) but that didn't help. Is there a workaround? For now I am downgrading to 1.1.4

Expected behavior

The expected behavior was to get a reference to a DeltaLake object.

Operating System

Linux

Binding

Python

Bindings Version

1.2.0 and 1.2.1

Steps to reproduce

No response

@rtyler did AWS put this behind a new feature gate?

[rtyler]

SSO specific dependencies were pruned in August since they were identified as unused in the crate. Since the Python dependency is not pulling in the dependencies it needs, it was lost. Womp Womp.

Update coming.
