Subject: [PATCH] Fix heartbeat timer leak for low-confidence detections, bump
 method buffer

Low-confidence mac_prefix_mfr hits no longer update fyLastDetTime/fyLastHB,
preventing them from keeping the heartbeat alive after a high-confidence
device leaves range. Bump FYDetection::method from 24 to 32 bytes so
"mac_prefix_soundthinking" (23 chars) has headroom.
