Nascent support for OOK TPMS transponders.
...
Apparently, Subaru and GMC. No CRC or other validation, no attempt to interpret packet contents yet.

Move TPMS taps to dsp_fir_taps.hpp.
...
Will soon use in proc_record.cpp.

For non-audio modes, don't bother muting audio.
...
It's assumed base class will start with audio muted.

Moved baseband temporary buffers back into class member variables.
...
Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.

Move baseband working buffers from member variables to stack.
...
It's temporary, after all...

More consistent use of pass-by-ref, const in baseband code.

Const/pass-by-reference a bunch more baseband stuff.

BasebandProcessor interface change to pass references, not copies.

Rename ::Packet to baseband::Packet. Remove IPC packet types.

Add TPMS initial demodulator implementation.
...
Right now, 2FSK, 19200 baud, +/-38400Hz deviation. No effort is made to check CRC/checksums or decode packets.
