/// \ingroup twa_misc
/// \brief Degeneralize a spot::tgba into an equivalent sba with
/// only one acceptance condition.
///
/// This algorithms will build a new explicit automaton that has
/// at most (N+1) times the number of states of the original automaton.
///
/// When \a use_z_lvl is set, the level of the degeneralized
/// automaton is reset everytime an accepting SCC is exited. If \a
/// use_cust_acc_orders is set, the degeneralization will compute a
/// custom acceptance order for each SCC (this option is disabled by
/// default because our benchmarks show that it usually does more
/// harm than good). If \a use_lvl_cache is set, everytime an SCC
/// is entered on a state that as already been associated to some
/// level elsewhere, reuse that level (set it to 2 to keep the
/// smallest number, 3 to keep the largest level, and 1 to keep the
/// first level found). If \a ignaccsl is set, we do not directly
/// jump to the accepting level if the entering state has an
/// accepting self-loop.
///
/// Any of these three options will cause the SCCs of the automaton
/// \a a to be computed prior to its actual degeneralization.
///
/// The degeneralize_tba() variant produce a degeneralized automaton
/// with transition-based acceptance.
