Using the project's docker-compose.yml and .env.example files, I got this error downloading models:

An error occured while synchronizing the model Systran/faster-whisper-small from the Hugging Face Hub: Cannot find an appropriate cached snapshot folder for the specified revision on the local disk and outgoing traffic has been disabled. To enable repo look-ups and downloads online, pass 'local_files_only=False' as input.

I noticed in faster-whisper.py that local_files_only=True was in a try/except. However, from what I can tell, an exception is never thrown here and we do not fall back to local_files_only=False as expected. My fix was to just remove the try/except altogether. This fixed model downloads for me. I am now able to edit .env to select whatever model I want and it will get downloaded

In order to use my patch here, I decided to try building the Dockerfile locally so I could include my patched version in the docker-compose.yml. However, I ran into build errors. My fork here I am trying to merge also fixes those. The commits should tell most of what changed

I updated faster-whisper because I couldnt get the pinned version to build with the rest of the deps. Using a later version and adding the requests library to requirements.txt seemed to fix the issue. I also pinned all the python dep versions in hopes that future Dockerfile builds are less likely to break

Also updated the default docker-compose.yml to also mount the /app/models dir so it's easy to tell which models are downloaded and persist these downloads between container creation/removal

Overall this PR just tries to get a minimal working example without changing too much. Should fix #92 and #155
