Hey,

Thanks a lot for the great library.

When installing TensorFlowTTS via pip it seems like a dependency is missing, e.g., the following commands fails:

!pip install TensorFlowTTS

from tensorflow_tts.inference import AutoConfig
from tensorflow_tts.inference import TFAutoModel
from tensorflow_tts.inference import AutoProcessor

because the package: german_transliterate can't be found. Only when doing

!pip install TensorFlowTTS
!pip install git+https://github.com/repodiac/german_transliterate

from tensorflow_tts.inference import AutoConfig
from tensorflow_tts.inference import TFAutoModel
from tensorflow_tts.inference import AutoProcessor

It works. It seems that german_transliterate is a necessary dependency to me -> should this maybe be installed automatically so that users can just do pip install TensorFlowTTS ? :-)

Here a colab to reproduce the problem.
