Dragonvoid is one of those weird bosses which consists of multiple
characters(?) that are structures and not even "normal" characters(??).
The first ID we used seemed to not catch the actual logs that are now
generated using an up-to-date arcDPS.

I'm not sure if the old ID was necessarily wrong, but for some reason,
it doesn't seem to match the actual ID that is currently used to log
this fight.

Many thanks to xyoz & neko for providing me with suitable log files!

There's not many useful things we can do with this log, other than
providing a way for downstream applications to identify those logs.

For a lot of applications, it can be useful to distinguish between logs
made in raids, fractals, ...

Note that we probably don't want further categorization (as for example
done in ezau).
