Remove config.h from Git; must be adapted by the user
...
A template for the config file is provided in src/config.h.template. It must be
copied to src/config.h and adapted for force users to set their own station
call sign.

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.
