mlat: fixed horrible bug in the solver. also noticed that [0,0,0] cannot contribute meaningful angular data, and so you still really want four stations on receive. there's still a bug in the solver somewhere that results in positions east of here not solving correctly.

Added SBS support for aircraft and flight ID
...
Looking at the SBS output, flight ID is just aircraft ID +
100. Aircraft ID is just a unique count to make parsing the output
file easier.
I'm not sure how useful this is but it makes us a step closer towards
mimicking the SBS.
I also pull out the ID for squitters 0, 4, and 5.

Added comments and change surface reports to MSG2
...
2 important things happened here:
-> Surface position reports where changed from MSG3 to MSG2. I believe
this is what that SBS message means.
-> MEs 1-4 are aircraft identification packets. Those should go to SBS
MSG1.

These are the 56 bit ADS-B message about altitude and such. Not as
cool as the the extended messages but still useful non the less.

Allow the user to set which antenna to use on the sub device

So .. from the terminal, "-A RX2", would set the device to use the RX2
antenna.The UHD manual will define your options. If the user puts in a
bad selection, it will complain and list the options.

Default int & dump to "no", use center sampling instead.
...
A learning experience I guess. If the pulse isn't REALLY square,
and instead is bandlimited in any way, integrate & dump doesn't work
as well as center sampling.
At any rate, the completely rewritten decoder should be both faster
and more sensitive than before.

Everything changed.
...
* Rewrote preamble detector. Uses integrate-and-dump along with correlator to perform optimal receive.
* No longer using framer. Determining packet length via header. Missing some anti-FRUIT stuff.
* Pulled out the slicer logic into its own function.
Lots of todos and fixmes.
