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.

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.
