Symlink Support

[ChiNoel-osu]

I was using faster-whisper and the downloaded model utilized relative symlink (to avoid duplications I suppose) but the webui (or the ctranslate2) doesn't like it:

models--guillaumekln--faster-whisper-large-v2\snapshots\f541c54c566e32dc1fbce16f98df699208837e8b is a folder that contains model files, those files are symlinks to the actual files at models--guillaumekln--faster-whisper-large-v2\blobs folder.

If I copy those files over and rename them, this error goes away. And the rest works flawlessly.
