In this commit, we add a new limit on the largest number of extra opaque bytes that we'll allow to be written per vertex/edge. We do this in order to limit the amount of disk space that we expose, as it's possible that nodes may start to pad their announcements adding an additional externalized cost as nodes may need to continue to store and relay these large announcements.
