Bandwidth files also need to respect MaxAdvertisedBandwidth and
RelayBandwidthRate/Burst. We need to specify that the relay descriptor
bandwidth rate and burst should limit the bandwidths in the file.

Torflow supports MaxAdvertisedBandwidth by putting relays in partitions
that match their bandwidth. Maybe it also does some other adjustments.

sbws can probably just do a min() using the measured bandwidth:
