feat: Enhance media recording capabilities by adding quality presets

[Abbhiishek]

• Added QualityPreset type with four options: "low" | "medium" | "high" | "ultra"
• Simple string-based configuration that users can easily understand

Mapped to appropriate settings: ✅

1. Low: 640x480@15fps, 500kbps video, 64kbps audio, VP8 codec
2. Medium: 1280x720@24fps, 1.5Mbps video, 128kbps audio, VP9 codec
3. High: 1920x1080@30fps, 4Mbps video, 256kbps audio, VP9 codec
4. Ultra: 3840x2160@60fps, 15Mbps video, 320kbps audio, VP9 codec

Users can now simply pass qualityPreset="high" instead of complex MediaRecorderOptions

Backward compatible - existing code continues to work unchanged

Example

// Simple usage - just specify the preset
const { startRecording, stopRecording } = useReactMediaRecorder({
  video: true,
  audio: true,
  qualityPreset: "high" // 1080p@30fps with optimized bitrates
});

// Advanced usage - preset with custom overrides
const { startRecording, stopRecording } = useReactMediaRecorder({
  video: { width: 1920, height: 1080 }, // Custom resolution
  audio: true,
  qualityPreset: "medium", // Will use medium bitrates but custom resolution
  mediaRecorderOptions: {
    videoBitsPerSecond: 2000000 // Override preset bitrate
  }
});
