Don't use DF18 when updating the known-Mode-S-address set.
...
DF18 transponders don't necessarily do Mode S, so we shouldn't assume
that Mode S messages from that address are valid merely because we
heard a DF18. If it really is Mode S equipped, we should hear a
DF11 at some point.

Overhaul mode A/C matching to be much cheaper.
...
The old matching process which tracked mode A values as pseudo-aircraft
got very, very expensive with a large number of mode A/C messages (and
with lots of single-bit errors, which seems common with a Beast doing
the reception)
Instead just count A/C messages directly into a 4096-entry array (which
is very fast) and periodically scan the mode S aircraft list to see if
we can match anything up (which is fixed overhead + cost proportional
to the number of mode S aircraft)

Restructure decoding to use a helper function to extract bit ranges

With forced inlining this is about as fast, and it is much less

it was before.

Comm-D ELM is actually DF 24..31, not just 24.
...
This DF is formatted with the first two bits as 1, and the next 3 bits
are part of the message rather than part of the DF code. So effectively
it spans 8 DF values if you are looking at the full 5 bits.

Fix up filter population so it's not completely insane.
...
The logic for DF11 was completely broken and inverted. How did this ever work??
Actually, the broken version kinda works because the only types of message that
can yield an address that's not already in the ICAO filter are DF11/17/18.
So DF=17; DF=18; and DF=11 with IID=0 would pass the broken logic and populate the
filter. All other DFs would pass the broken test, too, but they can only ever
re-add entries that were already there.
