Google Cloud Storage OAuth 2.0 Boto Plugin

This plugin enables the Boto library (version 2) to authenticate with Google Cloud Storage using OAuth 2.0 credentials, including service accounts and user accounts. It allows legacy Boto applications to interact with GCS. This library is deprecated; users are strongly encouraged to migrate to the official `google-cloud-storage` client library. The last release was 3.3 in March 2021, and the project is no longer actively maintained.
