* add AutoModelForTextToSpeech class

* add TTS pipeline and tessting

* add docstrings to text_to_speech pipeline

* fix torch dependency

* corrector 'processor is None' case in Pipeline

* correct repo id

* modify text-to-speech -> text-to-audio

* remove processor

* rename text_to_speech pipelines files to text_audio

* add textToWaveform and textToSpectrogram instead of textToAudio classes

* update TTS pipeline to the bare minimum

* update tests TTS pipeline

* make style and erase useless import torch in TTS pipeline tests

* modify how to check if generate or forward in TTS pipeline

* remove unnecessary extra new lines

* Apply suggestions from code review
