Storage.createFrom(BlobInfo blobInfo, Path path, BlobWriteOption... options) allows uploading directly from a file system. It would be useful to be able to upload a range of a file instead of the entire file. This feature would also be useful on MultiPartUploadClient, where it would be useful to be able to invoke uploadPart on a portion of a file.

Ideally, Storage.createFrom would have an overload that took a Path, offset, size and RequestBody.of would have an overload take took a Path, offset, size.
