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.
