Blind analytic normalization (BAN) for post-filtering

Parameters:
- ws (torch.complex64/ComplexTensor) – beamformer vector (…, F, C)
- psd_noise (torch.complex64/ComplexTensor) – noise PSD matrix (…, F, C, C)
- eps (float)
Returns: normalized beamformer vector (…, F)
Return type: ws_ban (torch.complex64/ComplexTensor)
