AWS Assume Role Lib

aws-assume-role-lib simplifies assumed role session chaining with automatic credential refreshing for boto3. As of version 2.10.0, released May 14, 2022, it provides an abstraction layer over `sts.AssumeRole` to handle credential expiration and session name generation, common in serverless environments like AWS Lambda. The library maintains a steady release cadence, with updates addressing new boto3 features and CLI support.
