VDDK always decompresses the chunks it retrieves. However, some callers may be interested in the compressed chunks, which may be forwarded to another service involved in the backup process. We'll add a read flag (skip_decompression). If set, the read operation will return a "ReadResult" container, containing a list of fragments and their compressed / decompressed lengths. If the returned buffer size matches the AIO buffer size (configurable), at most one fragment will be returned.
