Description
Expected Behavior
Currently, handle_missing=value adds a new column although the documentation says 'value' will encode a new value as 0 in every dummy column.
Furthermore, we need a test for this
Actual Behavior
adds a column instead of using all 0
Steps to Reproduce the Problem
from category_encoders import OneHotEncoder
import pandas as pd
he = OneHotEncoder(handle_missing="value")
data = [("foo", 1), ("bar", 2), (None, 6)]
data = pd.DataFrame(data, columns=["c1", "c2"])
print(he.fit_transform(data))
