0.21.0

🛠️ [0.21.0] Fixes

• Updated calls to Azure TTS Batch API so it should work again with the latest API version
• Added check for division by zero when calculating speech rate goal

📈 [0.21.0] New Features and Improvements

• Added force_always_stretch option to config, which will make it stretch the audio files after receiving from the TTS service even if it usually supports exact length, like Azure. Should come in handy if certain voices don't support specifying the exact length like some preview voices in Azure.

[0.21.0] Other Changes

• Some behind the scene changes to type hinting and enums instead of hard coded string references to improve reliability when making changes in the future
