- new: parallel downloads (about 5-6 times faster with 10 parallel downloads)
- new: partial https downloads are reducing the server load on NOAA side (about 5 times faster than requests through DODS server)
- new: unsage o grib2 format instead of netcdf (about 4 times faster due to transmission of compressed data)
- new. complete rewritten validation of correctness of the received data

- Due to slow and unreliable downloads via the DODS-server, the decision for a change of the complete data acquision to https-downloads had been made.
Also the support for the https downloads seems to be much better then for the DODS server.
