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.

All tags, all the time. Still some weirdness with set_history() that requires using the check widths in the framer & slicer.

Preamble now passes tags to framer.

Note: Using set_history cocks up the nitems_written() call.

You are seeing a couple of impossible altitudes and a couple of impossible longitudes. Looks like they're coming from the same aircraft. Possibly a nonstandard squitter? They pass checksum, but they don't contain the data you think they do.

Reorganized things quite a bit. Much cleaner output interface.

Made a single registry of output plugins which gets populated on init with classes to output on a socket, print to screen, database, etc. Next step is to implement a SQLite database class.

Fixed some bugs where I was treating sample data as an integer. Allows use with UHD without multiplying everything up by 64K. =)
...
Also changed the reference level printout to show dB instead of sample value. This seems more useful. 0dB is full scale.

Added uhd_modes.py, a UHD port of the usrp_modes.py program. Basically the same but takes a rate instead of a decimation.
...
Right now there's a 1e6 gain block in there because old USRP spit out roughly 1e6x data as USRP2. Haven't investigated this for USRP vs USRP2 yet. Don't know why blocks care, actually.
