AWS SigV4 Authentication for Requests

requests-auth-aws-sigv4 is a Python library that provides an authentication class to integrate AWS Signature Version 4 (SigV4) into the popular `requests` module. It simplifies the process of signing HTTP requests to AWS services, including API Gateway, Elasticsearch, and others, by handling credential retrieval from environment variables, parameters, or `boto3`. The current version is 0.7, with its last release in February 2021, indicating a mature and stable but less frequently updated library.
