Thomas Kolb 725a0ffd21 Ignore the squelch while receiving a packet
Before this commit, samples could be dropped during packet reception, which for
sure destroys the current packet and potentially the following one. Now samples
are stored even if the squelch „closes“, and decoding will potentially fail due
to high noise, but not due to missing samples.

Thomas Kolb f6404dd0ea Move payload CRC to layer 2
Layer 1 only does decoding of the FEC, but the CRC check for data integrity is
done in layer 2 now.

Thomas Kolb 65daa182ef Use the new logging system everywhere 2024-05-30 10:49:43 +02:00
Thomas Kolb d6eaef91cd Switch to new logging system
The new system supports:

- time-tagging of log messages
- message priority levels with a threshold below which they are not printed
- colored output of the message priority for easy identification
- compile-time disabling of all logging per C module

So far, it is integrated in the main and rx modules which generate most
messages. Other modules will be migrated in the future.
