FIX : Write - All the Sequences and Sequence Item are now written
            as 'no length' stuff, and a Sequence Delimitor aor an Item Delimitor
				is added a the end, when necessary.
            - A lot of brain-damaged images, that were read correctly are
		      now written correctly
				- length compatible BinEntry are now loaded correctly
				(even for odd groups)
            - Note : only Explicit Value Representation was checked.
				(question : is implicit VR really necessary for gdcm ?)
