dicom.Write: The Pixel data only supports OW type

[ChaoStraxcorp]

When I try to write a Dicom dataset to a file, I encountered the following error:

ERROR dicomio.veryifyElement: VR mismatch for tag (7fe0,0010)[PixelData]. Element.VR=OB, but DICOM standard defines VR to be OW

However, the pixel data should support both OW and OB types:

In pkg/tag/tag_definitions.go, the PixelData can only be OW.

Thanks for logging this. I think as part of the updates we'd like to make to the tag definitions (e.g. a follow on to #169) we will allow support for tags that can have multiple VRs. Definitely an important feature, and we'll take a look at this in the next few months!
