Cursor Location Value on classification raster throws python error

[Fabian Thiel]

By defaut cursor location value is in RBG, which is fine and useful, but for classification rasters it causes an error, after switching to "all band" mode it works again. So maybe we have to account for that (check if raster of type classification --> use "all bands" mode of cursor location value)
