This object supports loading of DICOM P10 dataset from a uri and caching it so it can be accessed
by the caller. This allows a caller to access the datasets without having to go through cornerstone's
image loader mechanism. One reason a caller may need to do this is to determine the number of frames
in a multiframe sop instance so it can create the imageId's correctly.
