Add FishAudioTTSService for real-time TTS processing via WebSocket

Instead of changing the example, please add a foundational example that is a minimal test case. You should mimic and one of the 07* foundational examples (e.g. https://github.com/pipecat-ai/pipecat/blob/main/examples/foundational/07d-interruptible-elevenlabs.py)

@MoeMamdouh Do you mind fixing the formatting issues? Take a look at https://github.com/pipecat-ai/pipecat?tab=readme-ov-file#setting-up-your-editor to setup your editor.

@MoeMamdouh I ran this and hit two issues:

1. There is popping at the start of each phrase
2. The last phrase is not being returned from Fish

The first issue can be resolved but the second seems like a Fish Audio issue. Have you noticed this and/or found a fix.

FYI: I started a parallel branch for this that confirms a bit better to the Pipecat TTS style: #899. We'll probably close this one out and work on the other, but before I do so, I want to see if you've resolved issue #294

(In the PR I posted, I was able to solve the popping issue by filtering on size. There may be a better way, but for now, it's fine.)

@MoeMamdouh I got a response from the Fish team and resolved the issue. I'm going to close this PR and we'll use #899 instead. Thanks so much for helping to get this started. I hope this service works well for you.
