    /* RAK (Richard Kirk, rak@cre.canon.co.uk) changes 14/7/99

       InputStream.skip() looped to check the actual number of
       bytes is read.

       Big/little-endian options on element length.

       Explicit check for each known VR to make mistaken identifications
       of explicit VR's less likely.

       Variables b1..b4 renamed as b0..b3.

       Increment of 4 to offset on (7FE0,0010) tag removed.

       Queries on some other unrecognized tags.
       Anyone want to claim them?

       RAK changes 15/7/99

       Bug fix on magic values for explicit VRs with 32-bit lengths.

       Various bits of tidying up, including...
       'location' incremented on read using getByte() or getString().
       simpler debug mode message generation (values no longer reported).

       Added z pixel aspect ratio support for multi-slice DICOM volumes.
