This function will get the number of values under the window center (0028,1050) element; this should also equal the number of values under the window width (0028,1051) element.

The Multi-frame Functional Groups module may have a Shared Functional Groups Sequence item, and/or a Per-frame Functional Groups Sequence item. Either of these items may have a Frame VOI LUT Sequence (0028,9132) item. If the following elements are not found at the top level in the dataset, this method looks in the Shared Functional Groups Sequence item and the Per-frame Functional Groups Sequence items.
