python: fix support for std::vector<const_twa_graph_ptr>
* spot/twaalgos/aiger.hh, spot/twaalgos/aiger.cc: Fix prototypes, as well as several error messages. * python/spot/impl.i: Implement an ad-hoc conversion for std::vector<const_twa_graph_ptr>. * tests/python/synthesis.ipynb: Use it to simplify the example. Adjust some comments.
