parity: add spot::colorize_parity()

Browse source 
These functions colorize automata with parity acceptance. They output
parity automata.

* spot/twaalgos/parity.cc, spot/twaalgos/parity.hh: Here
* tests/core/parity.cc: Add tests for spot::colorize_parity()
* tests/python/parity.ipynb: Add documentation about
spot::colorize_parity()

/// \brief Colorize an automaton with parity acceptance
///
/// An automaton is said colored iff all the transitions belong to exactly one
/// acceptance set. The algorithm achieves thiat by removing superfluous
/// acceptance marks. It may introduce a new set to mark the transitions with
/// no acceptance sets and a second set may be introduced to keep the style.
/// The input must be an automaton with a parity acceptance, otherwise an
/// invalid_argument exception is thrown.
///
/// \param aut the input automaton
///
/// \param keep_style whether the style of the parity acc is kept.

/// \return the colorized automaton
