Data extraction of some samples in n-bit files

[constantinius]

When reading not multiple of 8 bit unsigned data in pixel interleaved images, some samples are read wrongly.

I'm seeing something similar. readRasters on an 11-bit TIF sometimes gives me values above the top pixel value of 2047. ~1% of my pixels will be from 2048-2121.
Any tips on where to look to try to address this?

Note: When it happens, it's only on the reduced resolution (internal) overviews. When I zoom in to full resolution, the problem is not there.

Adding this to my gdal_translate fixed my issue. Sorry for the false alarm.
