add emotion and emotion_scale parameter

Summary by CodeRabbit

• New Features
  • Added optional “emotion” and “emotion_scale” parameters to audio speech synthesis requests, allowing finer control over vocal expressiveness.
  • These parameters are fully optional; existing integrations continue to work unchanged.
  • When provided, “emotion” selects the desired emotional tone, and “emotion_scale” adjusts its intensity for more nuanced output.

Poem

A nibble of code, a hop of delight,
New tones to speak—soft day, bold night.
Emotion scales set, the waveform sings,
Carrots in cache and joyful pings.
I twitch my ears at PRs so sweet—
Now our speech can smile and beat. 🥕🐇
