Fix for e_control not used during synthesis #200

[lordzuko]

The e_control parameter fixed in the , is not correctly used in work/FastSpeech2/model/modules.py -> VarianceAdaptor.forward function.

Currently:

        if self.energy_feature_level == "phoneme_level":
            energy_prediction, energy_embedding = self.get_energy_embedding(
                x, energy_target, src_mask, p_control
            )
            x = x + energy_embedding
            

and

        if self.energy_feature_level == "frame_level":
            energy_prediction, energy_embedding = self.get_energy_embedding(
                x, energy_target, mel_mask, p_control
            )
            x = x + energy_embedding

Fix:

        if self.energy_feature_level == "phoneme_level":
            energy_prediction, energy_embedding = self.get_energy_embedding(
                x, energy_target, src_mask, e_control
            )
            x = x + energy_embedding

and

        if self.energy_feature_level == "frame_level":
            energy_prediction, energy_embedding = self.get_energy_embedding(
                x, energy_target, mel_mask, e_control
            )
            x = x + energy_embedding
