Implement the '__init__' function of the TimeSeriesPrecision class

[nocotan]

Summary

Implement the __init__ function as follows:

def __init__(self, beta=1.0, alpha=0.0, cardinality="one", bias="flat"):
       """
       docstring
       """

        assert (alpha >= 0) & (alpha <= 1)
        assert beta > 0
        assert cardinality in ["one", "reciprocal", "udf_gamma"]
        assert bias in ["flat", "front", "middle", "back"]

        self.beta = beta
        self.alpha = alpha
        self.cardinality = cardinality
        self.bias = bias

Goal

Make it possible to initialize the TimeSeriesPrecision class.
