Title: support for named style (classgroups) for raster layers

fixes #2804

This change makes it possible, to configure classgroups for raster layers. This can be useful for palette based raster data sources:

CLASS # coloured
GROUP 'coloured'
STYLE
END
END

CLASS # grey
GROUP 'grey'
EXPRESSION ([pixel] = 0)
COLOR 255 255 255
END

CLASS # grey
GROUP 'grey'
EXPRESSION ([pixel] = 1)
COLOR 128 128 128
END
