v0.48

New additions in v0.48:

• Tweaking the bandwidth setting for the SDRplay increasing message reception slightly
• new model that is less sensitive to frequency drift. You can run this model using the switch -go AFC_WIDE on (which is now the default as well). Running the new model setting and the previous default model on a file with ~410 messages and artifically shifting the frequency to simulate dongle frequency instability, shows the following:

Initial observation is that the new model (orange) has a similar message count if the dongle has no frequency offset compared to the current default model (blue), i.e. for the case of zero shift. The new model hears a similar number of ships but, as hoped, seems less affected if the dongle is off by +/- 5 ppm and not corrected by the -p switch.
