Implement Data Transforms.

[hasanemirakin]

Implement data transformations functions such as power transforms, standardization and normalizations. Priorities are:

-Box-Cox (https://en.wikipedia.org/wiki/Power_transform#Box%E2%80%93Cox_transformation) -Standardization (https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.StandardScaler.html) -Normalization (https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.MinMaxScaler.html)

Please share if you have any other methods in mind.

box_cox is implemented, working on standardization and normalization

standardization and minmaxscaling was implemented
