Encode Values

Encodes values in a column through a variety of methods:
Label Encoding: Encode target labels with value between 0 and n_classes-1. See scikit-learn's LabelEncoder for full documentation.
Target Encoding: Encode a categorical column with the average value of a target column for the corresponding value of the categorical column. See scikit-learn's TargetEncoder for full documentation.
One Hot Encoding: Encode a categorical column as a 0 or 1 for each possible category, each of which will be it's own row.
