Implement expressions for the spin factor based on covariant tensor formalism Make it much simpler to switch between formalism options via new functions in LauResonanceMaker: - setSpinFormalism, setBWType, setBWBachelorRestFrame - default settings are unchanged (and are equivalent to setting LauAbsResonance::Zemach_P, LauBlattWeisskopfFactor::BWPrimeBarrier, LauBlattWeisskopfFactor::ResonanceFrame, respectively) close #70
