dmiller 875a51fb0f Be more parallel with ARP discovery ...

Two essential changes:

1. (ab)Use the ratelimit detection feature to hold off sending retransmissions,
preferring to send new ARP probes. Late responses will still be recorded, but no
longer counted as drops. This also gives each target the longest amount of time
to respond.

2. Send timing pings much more frequently. Since we're not sending any
retransmissions until timeout + ratelimit, we wouldn't otherwise have any data
on drops in order to speed up or slow down.

Results are faster ARP scans with fewer missed targets. See #92.
