Pygmtools

* Add notes for Koopmans-Beckmann's QAP
* Other minor fixes by rogerwwww in https://github.com/Thinklab-SJTU/pygmtools/pull/99


**Full Changelog**: https://github.com/Thinklab-SJTU/pygmtools/compare/0.5.1...0.5.2

What's Changed
* Pygmtools is [published in JMLR](https://jmlr.org/papers/v25/23-0572.html)!
* Update download urls for test_dataset.py by heatingma in https://github.com/Thinklab-SJTU/pygmtools/pull/96
* Improved docs & examples
* ``c_astar`` modules will be imported only on-demand to avoid https://github.com/Thinklab-SJTU/pygmtools/issues/92 for most users
* **Backward compatibility broken**: ``pygm.astar`` now works as a Lawler's QAP solver, just as other ``pygm.classic_solvers``. If you are expecting the old behavior as a specialized GED solver, please use ``pygm.genn_astar``
