feat(deflated): Added support for reading datasets with deflated transfer syntax

[PantelisGeorgiadis]

Added support for reading datasets with Deflated Explicit VR Little Endian transfer syntax (1.2.840.10008.1.2.1.99). The deflated transfer syntaxe compress the whole dataset (except the file meta information header), using the standard “deflate” mechanism as used in gzip. In case the transfer syntax is recognized as Deflated Explicit VR Little Endian, the reading stream is "promoted" to a deflated reading stream, which internally uses pako to inflate the dataset bytes, prior reading them.

Thank you for your review @pieper! You can find the deflated sample file I used here. I would be grateful if you push the zip file to the data repo so I can update this PR.

Great - here's the release with the files as zip.
