GDALRaster GDT_Byte Datatype mapped wrongly to ctypes

Description

The constant mapping of GDAL datatypes to ctypes datatypes in contrib.gis.gdal.raster.const.GDAL_TO_CTYPES wrongly maps GDT_Byte to c_byte, when it should be c_ubyte. GDT_Bytes are unsigned 8 bit integers.

Here is the patch for it

Sorry for not noticing this earlier, numpy does automatic overflow mapping for bytes data, so I did not realize that this was a problem until today.
