fix(one-to-many routing): in the case of routing networks with one or more divergences (reaches routing to more than one reach), the downstream connections were still being cast to ints, and therefore weren't identified as being within the stream network (of string line-ids). Remove type-casting here as it should be done in other contexts when the data are read in.
