Add all bwauth measurements (from votes)
As discussed in legacy/trac#16020 (moved), it would be handy to have all measurements from bwauths included in onionoo data.
The main concert is the additional workload, Karsten wrote: " Including all bwauth measurements would certainly be handy, but that would require parsing votes which we don't do right now. Onionoo is already choking on parsing all the descriptors published every hour, and votes are not exactly tiny. I'd say don't expect this to happen anytime soon. But I agree that it would be really useful to have. "
