Parse and Build Amazon S3 URLs

s3urls is a small, dependency-free Python library designed to parse and build Amazon S3 URLs. It provides utility functions to extract bucket names and keys from S3 URIs (e.g., `s3://bucket/key`) and HTTP/HTTPS S3 object URLs, as well as to construct such URLs. The current version is 0.0.3, with its last release in 2018, indicating a stable but infrequently updated project.
