Fix the pickle error when dumping an estimator

[imxtx]

This fix #83. When saving an estimator, the dump method will report an error due to module class members and lambda functions.

Solved two issues:

1. Pickle does dot support dumping module objects. There is no need to put the creator as a class member of GASearchCV and GAFeatureSelectionCV.
2. Lambda creates anonymous function objects that don't have names and can't be found by the pickle loader. See https://stackoverflow.com/a/72339613.

hI @imxtx It looks good, the only change I'd request is to rename the function from getter_fittness_values to ind_fitness_values, just to a keep track of the names from the DEAP package
Thanks!
