Closes #578
This PR implements detection of absent-mindedness in extensive-form games, where a player can re-enter an information set on a single path of play.
Changes:
BuildInfosetParents()traversal to detect and record absent-minded information sets.IsAbsentMinded()in C++ and a correspondingis_absent_mindedproperty in Python, mirroring the logic ofIsPerfectRecall().
