Support SN3D normalization #21

Hi @jishnub, thanks for providing this library. I've been using it for Ambisonics 3D audio processing. I saw you adding new normalizations. I was wondering if you could add an option for SN3D normalization with no CS phase term? Like the AmbiX format here. Thanks!

Currently I have only added normalization for the associated Legendre polynomials. Would you like normalization options for these, or for the spherical harmonics?

Would the normalization of the associated Legendre polynomial apply to the Spherical Harmonics too? The Ambix format needs the normalization on the whole spherical harmonic.
