like something we should fix, yeah.
One to fix this is to run two instances of the PT on different addresses.
But I don't think the extra-info format allows that. And it doesn't allow
multiple IP addresses, either:
https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n1211
So we either need to:
1. use a different transportname, like obfs4-ipv6
2. allow IPv4 and IPv6 lines with the same transportname
3. add an "ipv6=" arg to the arglist
Option 3 is more like what we do for authorities and fallbacks. And it
avoids issues with having two lines for the same bridge, which has caused
subtle bugs in the past.
