imgproxy can process images from S3 buckets. To use this feature, do the following:
1. Set `IMGPROXY_USE_S3` environment variable as `true`;
2. [Setup credentials](#setup-credentials) to grant access to your bucket;
3. Use `s3://%bucket_name/%file_key` as the source image URL.
1. Specify AWS region with `IMGPROXY_S3_REGION` or `AWS_REGION`;
3. [Setup credentials](#setup-credentials) to grant access to your bucket;
4. _(optional)_ Specify S3 endpoint with `IMGPROXY_S3_ENDPOINT`;
5. Use `s3://%bucket_name/%file_key` as the source image URL.
