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.

rip out the energy stuff, int-and-dump filter takes care of it

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.

Preamble detector cleanup. Better for >2 samps/symbol.

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.
