#593: [raster] Add a ST_BandIsNoData function

Comment(by jorgearevalo):
Commited some changes in r6736:[[BR]]
- Created function ST_SetBandIsNodata[[BR]]
- Deleted the isnodata checking from loader (it did nothing). Check the
pixel values while loading them is not a trivial task. The WKB for band
header is generated before the WKB for band data. So, we should modify WKB
for band header after checking pixels when needed. I think that is not a
priority right now.
