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.

Add support for passing manually various device parameters
...
All flowgraphs now support user defined parameters for most of their
configuration capabilities. These include:
* RF gain
* IF gain
* BB gain
* Custom device arguments for setups with multiple SDRs. These
coresponds to the 'Device arguments' field of the Osmocom source block.
* Antenna selection for devices with multiple antennas (USRPs, etc)
Changing sampling rate is not supported (yet).
For listing the arguments just execute <flowgraph> --help in a terminal
window.

Reduce RTL SDR buffers size
...
In memory limited devices like RPi, the default buffer allocation scheme
of the RTL driver causes problems to the async transfer engine.
This prevented the flowgraphs to start.
Reducing the buffer size fixes this problem.

Fix gnuplot issue
...
In some cases (crash, inproper termination) a flowgraph failed to
produce a binary file that had exactly the proper number of float
numbers in order the gnuplot script to be able to convert it in a matrix
representation.
The updated script tries to truncate the binary file in such a way so it
can be converted into a matrix. This will allow waterfall images to be
created even after a crash.
System should have the "truncate" command line utility installed which
is part of GNU GNU coreutils.
