Feature request. Early stopping

[FiksII]

Good day. If it possible to add 'early_stopping' feature? Sometimes I want to stop the process if it's stuck.
I can add it.

How should I test it? It seems you have a lot of "personal" tests for algorithms, but no one general tests.

[Evolutionary-Intelligence]

You can write a simple test case. We (at least two core developers of this libary) will check and test it. After passing our test, we will add it in the new version (0.0.76).

@FiksII We have upgraded your testing code as follows: https://github.com/Evolutionary-Intelligence/pypop/blob/main/pypop7/optimizers/core/_test_optimizer.py. In your initial version, only one test case is run, though for is used.

@FiksII We also upgraded your Python code for class optimizer: https://github.com/Evolutionary-Intelligence/pypop/blob/main/pypop7/optimizers/core/optimizer.py. For two private members, we use _ as the prefix (a standard Python practice).
