allow 1-bit colormaps for TIFF images
The TIFF specification seems to only allow for 4-bit and 8-bit
colormaps. However at least Microsoft's XPS viewer also accepts 1-bit
colormaps and our current code handles this case already anyway.
See https://code.google.com/p/sumatrapdf/issues/detail?id=2562 for a
sample document.
