    Add subring numbers to their names to improve log clarity.
    
     * CHANGE bridgedb.Filters.filterAssignBridgesToRing() to rename
       generated filter functions to include the subring number and the
       total number of subrings, e.g.
         filter.__name__ = "filterAssignBridgesToRing3of4"
    
     * CHANGE bridgedb.Bridges.FilteredBridgeSplitter.addRing() to name
       subrings based on their number.  For example, if an HTTPSDistributor
       has 3 total subrings and subring 3/3 is for known-proxy users, then
       the subrings would be named like:
         - HTTPS-IP4-1of3
         - HTTPS-IP4-2of3
         - HTTPS-IP4-Proxy
         - HTTPS-IP6-1of3
         - HTTPS-IP6-2of3
         - HTTPS-IP6-Proxy
