Remove CW matched filter block
...
CW decoding using match filtering is pretty much useless in LEO.
The information about the tone frequency is very rare and carrier
oscillations during the satellite pass reduce significantly the
performance.
The new next CW decoder is based on the autocorrelation of the received
signal.

Change NOAA output naming scheme
...
NOAA APT decoder will create a file without a timestamp. The
satnogs-client will be resposible to append the proper timestamp.
This change was necessary to avoid the time offset between the start of
the observation timestamp that the APT decoder appends to the filename
and the end of the observation that the client takes into account.
