Multer S3

Streaming multer storage engine for AWS S3. Version 3.0.5 uses AWS SDK v3 with the @aws-sdk/lib-storage Upload class, while v2.x uses AWS SDK v2. It streams multipart uploads directly to S3 without buffering to disk, making it scalable for high-traffic applications. Requires Node >= 12 and peer dependency @aws-sdk/client-s3 ^3.0.0.
