When loading chemkn file, allow duplicate reactions of other kinetic types.
When loading chemkn file, allow duplicate reactions of other kinetic types.

Handle them like template reactions with differing transition states and let
them stay as separate reactions rather than combining the kinetics into a
MultiArrhenius or MultiPDepArrhenius object.

I'm sending out a logging.warning anyway.
