Implements pause and resume capabilities for the EMD (Earth Mover's Distance) solver, allowing long-running optimizations to be interrupted and continued from their exact state. Changes: - Modified EMD_wrap() signature to accept checkpoint parameters for saving and restoring complete internal solver state (flow, potentials, tree structure) - Added saveCheckpoint(), restoreCheckpoint(), and runFromCheckpoint() methods to NetworkSimplexSimple class in network_simplex_simple.h - Extended emd_c() Cython wrapper to handle checkpoint dictionaries with 12 fields (10 arrays + 2 scalar arc counts) - Added 'checkpoint' and 'return_checkpoint' parameters to emd() Python API - Includes search_arc_num and all_arc_num scalars in checkpoint to preserve initialization state required by start() method Tests: - Added test_emd_checkpoint() for basic save/resume functionality - Added test_emd_checkpoint_multiple() for multiple pause/resume cycles - Added test_emd_checkpoint_structure() to verify checkpoint field integrity
