      speed up parsing of bin logs · 023ebcd1
      Andrew Tridgell authored 
      use a dictionary of sets to record which instances of a message have
been seen before. This avoids us having to parse all instance based
messages fully during the load.

as we have added more instance messages the time to load the log has
become progressively longer. With this change it now becomes short
again

on a recent 160MByte quadplane log the time to load the log with this
change drops from 39.9s to 6.5s
