Don't try to read bz2 file as grib2 it's too slow #265

Hi,

Temporary workaround for slow bz2 compressed grib1 file.

Bzip2 backward seek is very slow because it has to re-open the file and decompress it again from the start. Our grib2 decoder seek backward...

A proper solution would be to not seek backward, we already decompressed file twice , first in Terrain::loadMeteoDataFile and it the decoder so it shouldn't be too hard.
