Implement GNSS-SDR.GPS_banned_prns, GNSS-SDR.Galileo_banned_prns, GNSS-SDR.Glonass_banned_prns, and GNSS-SDR.Beidou_banned_prns configuration parameters. The user can specify lists of satellites that will not be processed (e.g. GNSS-SDR.Galileo_banned_prns=14,18 since Galileo E14 and E18 satellites are not usable for PVT). Documented at https://gnss-sdr.org/docs/sp-blocks/global-parameters/\#banned-satellites Inspired by #397

from the binary and can help to reduce its size and speed up the receiver. In
binaries with enabled logging, it can be still disabled by passing the command
line flag `--minloglevel=3` to `gnss-sdr`.
- Defined new `GNSS-SDR.GPS_banned_prns`, `GNSS-SDR.Galileo_banned_prns`,
`GNSS-SDR.Glonass_banned_prns` and `GNSS-SDR.Beidou_banned_prns` configuration
parameters. The user can specify lists of satellites that will not be
processed (e.g., `GNSS-SDR.Galileo_banned_prns=14,18` since Galileo E14 and
E18 satellites are not usable for PVT). Satellites on those lists will never
be assigned to a processing channel.
