Pulls in over 100MB of dependencies!

I have a small codebase, with a number of third party libs, including other AWS libs for rds-data, s3, etc - it totals ~60MB including node_modules folder.

Adding this as a dependency has added over 100MB of additional dependencies! Surely that cant be necessary? Its almost half the lambda budget solely for IAM authentication with keyspaces...

Begin by inspecting the package manifest and dependency tree to identify which dependencies account for the added size, then compare the resulting bundle with the project's existing AWS and Cassandra-related libraries. Done means the authentication plugin's dependency footprint is reduced without losing its documented IAM authentication behavior.
