Soto S3 Transfer

https://github.com/soto-project/soto-s3-file-transfer

Swift library for syncing a local folder with S3.

Plan:

try await s3FileTransfer.sync(
    from: "/Users/me/planet-site/", 
    to: S3Folder(url: "s3://my-bucket/planet-site")!,
    delete: true
)

Multiple sites in one bucket or one bucket per site?
