Load the initial values for Wilson coefficients from
        a file-like object or a string in WCxf format.

        Note that Standard Model parameters have to be provided separately
        and are assumed to be in the weak basis used for the Warsaw basis as
        defined in WCxf, i.e. in the basis where the down-type and charged
        lepton mass matrices are diagonal.
