python: add a spot.automata(filename) interface, yielding automata
* src/hoaparse/fmterror.cc, src/hoaparse/public.hh, src/hoaparse/hoaparse.yy (hoa_stream_parser::parse_strict): New method that raises an exception whenever a syntax error is encountered. * src/ltlparse/public.hh (parse_error): Move ... * src/misc/common.hh: ... here. * wrap/python/spot_impl.i: Wrap the hoa output. * wrap/python/spot.py: Implement spot.automata. * wrap/python/tests/automata-io.ipynb: New test. * wrap/python/tests/Makefile.am: Add it.
