faster-whisper 0.7.0

Improve word-level timestamps heuristics

Some recent improvements from openai-whisper are ported to faster-whisper:

• Squash long words at window and sentence boundaries (openai/whisper@255887f)
• Improve timestamp heuristics (openai/whisper@f572f21)

Support download of user converted models from the Hugging Face Hub

The WhisperModel constructor now accepts any repository ID as argument, for example:

model = WhisperModel("username/whisper-large-v2-ct2")

The utility function download_model has been updated similarly.

Other changes

• Accept an iterable of token IDs for the argument initial_prompt (useful to include timestamp tokens in the prompt)
• Avoid computing higher temperatures when no_speech_threshold is met (same as openai/whisper@e334ff1)
• Fix truncated output when using a prefix without disabling timestamps
• Update the minimum required CTranslate2 version to 3.17.0 to include the latest fixes
