bin: add a --check option for automata outputs

Browse source 
This currently only allows extra check for stutter invariance.

* src/bin/common_aoutput.cc: Add check option,
and test stutter invariance.
* src/twaalgos/stutter.cc, src/twaalgos/stutter.hh
(check_stutter_invariance): New function.
* src/tests/stutter-tgba.test: Test it.
