Uses `RobustImputer` on 1D inputs of labels

- Only uses the `RobustImputer` strategy `constant` and fills using `np.nan`
- Default behavior encodes non-float and non-finite values as nan values in
the target column of a given regression dataset
Parameters
----------
mask_function : callable -> np.array, dtype('bool') (default=None)
A vectorized python function, accepts np.array, returns np.array
with dtype('bool')
For each value, if mask_function(val) == False, that value will
be imputed. mask_function is used to create a boolean mask that determines
which values in the input to impute.
Use np.vectorize to vectorize singular python functions.
