[ITK] Read dicom files according to tags

[Lambert Zijp]

Hi Xie,

Just out of curiosity, why do you want to read images with a specific
level/window pre-set? After all, those are just (recommended) *viewer*
settings. I mean, you can set level/window to whatever you want, but the
pixel-data remain the same.

Greetings,
Lambert
