Refactor out some magic numbers and conditionals
Warn when we are using an older version of elasticsearch. The version is so old I'm not worrying about it for the moment
Mark everything we haven't decoded as data
This is not a problem actually. I have tested this out with the HTTP dissector and it reports the length of the last packet that completed the reassembly
Deal with compression
Rename magic number to token as this is what it is called in the elasticsearch source
Deal with compression with response messages
