I believe that ReadBlock() is not available from the SWIG interface because
it would mean a need for a batch of GDALRasterBlock interfaces.  Direct
access to raster blocks is mostly for internal use within drivers and I
now try to discourage even C/C++ applications from using it.

This could be reconsidered if there was a compelling need, but I'd rather
have applications use RasterIO() and it's SWIG equivelents.
