Fix LMMAES

[arahi10]

This pull request is for this issue.

Compared with implementation in numpy, the original LM_MA_ES in evosax seems to be incorrect wrt default parameters settings and parameters update expressions so I write a code corresponds to numpy implementation.

I used black linter and tested by evosax/tests/test_strategy_api.py. This is my first contribution, so please tell me if there are any problems.
