AWS Lambda SnapStart Python Runtime Hooks

The `snapshot-restore-py` library provides runtime hooks for AWS Lambda SnapStart, enabling Python functions to execute code before a snapshot is taken and after a function is restored from a snapshot. This significantly reduces cold start times for Python 3.9+ Lambda functions by allowing the caching and reuse of an initialized execution environment. It is currently at version 1.0.0 and is actively maintained by AWS, with releases primarily driven by Lambda runtime updates or feature enhancements.
