About making botocore an optional dependency

[pushkarnimkar]

Describe the improvement

I am installing cohere-python in a docker image. I don't use any AWS service, nevertheless the library still installs the boto3 dependency that takes around 25 MB of space. Removing the dependency or making it optional can reduce size of the image.

Example of optional dependencies when using poetry.

Thank you!
