Implement FEC2 Erasure Correction in Galileo E1B INAV message

Browse Source 
This feature is configurable, disabled by default.

Added a benchmark for the Reed Solomon decoder.

Make the RS decoder to accept both shortened or unshortened codes

### Improvements in Availability:
- Added the reading of reduced clock and ephemeris data (CED) in the Galileo E1B
INAV message introduced in Galileo ICD v2.0. If the reduced CED is available
before the full ephemeris set, it is used for PVT computation until the full
set has not yet been received. This can contribute to shorten the
INAV message introduced in Galileo OS SIS ICD Issue 2.0. If the reduced CED is
available before the full ephemeris set, it is used for PVT computation until
the full set has not yet been received. This can contribute to shorten the
Time-To-First-Fix.
- Added the exploitation of the FEC2 Erasure Correction in the Galileo E1B INAV
message introduced in Galileo OS SIS ICD Issue 2.0. This can contribute to
shorten the Time-To-First-Fix. Since the added computational cost could break
some real-time configurations, this feature is disabled by default. It can be
activated from the configuration file by adding
`TelemetryDecoder_1B.enable_reed_solomon=true`.
### Improvements in Maintainability:
