crates/bench reads TABLE_DUMP_V2 dumps (RFC 6396) as published by RIPE RIS
and RouteViews, and `--bench real_table` runs the Adj-RIB-In on one. The
dumps are not checked in; crates/bench/data/README.md says how to fetch
one. Without a dump the benchmark says so and does nothing.
It also prints what in the table decides the cost of a RIB: routes per
prefix, distinct attribute sets, how many routes share a set, and how much
the sets are shared between peers.
