Expose circparameters_from_netparams

17:34 <+nickm> sounds okay; I'm fine with a lot of stuff, even a `pub fn 
               circparameters_from_netparams`  in circmgr.
17:34 <+nickm> I'd prefer not to introduce a dependency from tor-netdir to 
               tor-proto if there is not one already
17:35 <+Diziet> tor-circmgr lib.rs l.140 ish already has   fn 
                from_netparams(inp: &NetParameters) -> CircParameters {
17:35 -!- anr1234[m] [~anr1234ma@2001:470:1af1:101::e4ce] has quit [Quit:

17:36 <+Diziet> If you are OK with hoiking that out and exposing it, that would 
                solve my problem very nicely
17:36 <+nickm> yeah, we could just rename and expose that and I wouldn't 
               complain
17:36 <+nickm> maybe put it in tor_circmgr::build assuming that module is 
               public?
17:37 <+Diziet> I'll call it circparameters_from_netparams like you suggest
