Directly specify optional dependencies `awscli` and `boto3`

[jakob-keller]

Hi!

Over at aio-libs/aiobotocore#1424, I am proposing to retire the aiobotocore optional dependencies / "extras" boto3 and awscli in a future major release.

s3fs is currently relying on those in:

s3fs/setup.py

Lines 39 to 40 in f8d4e41

	"awscli": [f"aiobotocore[awscli]{aiobotocore_version_suffix}"],
	"boto3": [f"aiobotocore[boto3]{aiobotocore_version_suffix}"],

Would it be possible for s3fs to specify those dependencies directly?

"awscli": [f"aiobotocore{aiobotocore_version_suffix}", "awscli"], 
"boto3": [f"aiobotocore{aiobotocore_version_suffix}", "boto3"], 

Modern dependency resolvers in pip, uv and so forth should not have any trouble with that and install the same set of packages as before.

Any thoughts? Am I missing something?

There have been consistent ongoing issues on this repo about people installing s3fs and boto3 and either ending up with something incompatible, or pulling in a very old s3fs (from before depending on aiobotocore). I don't know if substituting as you suggest would be foolproof or not - happy to hear feedback from those that know or wish to try it.

Agree about awscli - boto3 is the one that really matters here.
