Modular ElevenLabs Provider

This library provides a modular implementation of the ElevenLabs provider following the same architecture pattern as other providers.

Key Features:

• High-quality text-to-speech synthesis
• Speech-to-text transcription
• Voice cloning and customization
• Multiple language support
• Real-time streaming capabilities
• Modular architecture for easy maintenance

Usage:

import 'package:llm_dart/providers/elevenlabs/elevenlabs.dart';

final provider = ElevenLabsProvider(ElevenLabsConfig(
  apiKey: 'your-api-key',
  voiceId: 'JBFqnCBsd6RMkjVDRZzb',
));

// Text-to-speech
final ttsResponse = await provider.textToSpeech(TTSRequest(
  text: 'Hello, world!',
  voice: 'JBFqnCBsd6RMkjVDRZzb',
));

// Speech-to-text
final sttResponse = await provider.speechToText(STTRequest.fromFile(
  'path/to/audio.wav',
));

// Get available voices
final voices = await provider.getVoices();
for (final voice in voices) {
  print('${voice.name}: ${voice.id}');
}
