Implemented Power Split and Guard Split (#699)

* Implemented Power Split and Guard Split

* Update changeStat method to use summonData for Pokemon stats

This commit modifies the `changeStat` method in the `Pokemon` class to use the `summonData` object for updating Pokemon stats instead of directly modifying the `stats` object. This change ensures that the updated stats are correctly reflected in the `summonData` object, which is used for battle calculations and other related operations.

Refactor the `getStat` method to check if `summonData` exists and return the corresponding stat value from `summonData.stats` if it does. Otherwise, return the stat value from the `stats` object.

This change improves the accuracy of stat calculations during battles and ensures consistency between the `stats` and `summonData` objects.

* Added documentation for Power Split and Guard Split + linting

* removed incorrect files

* Removed incorrect folder

* removed unnecessary import

* Added documentation for getStat and changeSummonStat methods

* New description for getStat()

* Adjusting function descriptions

* adjusted descriptions according to guideline
