mfa for multi speaker.

[leon2milan]

In the code, group MFA inputs for better parallelism. For multi speaker, it maybe go wrong.
For input g_uang3 zh_ou1 n_v3 d_a4 x_ve2 sh_eng1 d_eng1 sh_an1 sh_i1 l_ian2 s_i4 t_ian1 j_ing3 f_ang1 zh_ao3 d_ao4 i2 s_i4 n_v3 sh_i1.

The mfa code is borrowed from the official repo of NATSpeech. Unfortunately I have not studied the mfa module in depth. We encourage you to push your commits on multi-speaker chinese corpus. Thanks a lot!

[leon2milan]

hello, I push a commit. But I don't know it suits for your planning. The parameter of mfa_group seems unnecessary. It doesn't prompt the train speed compared with wetts(it uses version 2.1.0). Also need add the parameter of spk_name.
