Prop 313: 8.2. Analyse and Monitor IPv6 Stats

As part of Sponsor 55, the Tor Metrics team will analyse the new IPv6 connection and bandwidth statistics.

We will use their analysis to provide IPv6 progress reports.

We might also discover some bugs in tor's IPv6 stats code during the first analysis.

See proposal 313, section 8.2, metrics analysis part: ​https://gitweb.torproject.org/torspec.git/tree/proposals/313-relay-ipv6-stats.txt#n355

The definitions of these statistics are in proposal 313, sections 4 and 5: https://gitweb.torproject.org/torspec.git/tree/proposals/313-relay-ipv6-stats.txt#n118
