Philipp Schlehuber 5ddac258e1 Introduce new ways to split an automaton
The explicit way of splitting suffers if there are
too many input APs, two new ways of splitting
are introduced as well as a heuristic to chose
between them.

* NEWS: update
* spot/twaalgos/synthesis.cc,
spot/twaalgos/synthesis.hh: New fonctions
* bin/ltlsynt.cc: Add corresponding option
