PDFBOX-4326: override colorspace to avoid wrong number of 3 colors; provide 
passing integer RGB raster for possible future use

> The EOF exception is because SampledImageReader expects a stream that is 3x 
> longer than actually appears, because the colorspace is said to have 3 colors 
> instead of 1. This is because the JPEG2000 plugin returns an image with 
> IndexColorModel which references three colors.
> There are two ways to solve this and both worked: the slower is to convert to 
> RGB which requires another change when reading the raster (because the raster 
> is now made of integers), the faster is to force a gray colorspace. I use the 
> later but keep the change I made in passing the integer RGB raster, we may 
> need it some day.
> I'm making the change only for the trunk for now, and to the 2.0 branch after 
> release of 2.0.12.
