Merged: No

This PR implements the TrackExtractor class for extracting comprehensive track data from Spotify web pages, including metadata, preview URLs, and synchronized lyrics.

Features Implemented

Extract track metadata (name, ID, URI, duration, artists, album details)
Extract preview URLs and playability status
Extract synchronized lyrics with timing information when available
Handle both regular and embed Spotify URLs seamlessly
Support URL validation and conversion between formats

Implementation Details

Created a modular architecture with separation of concerns:
- TrackExtractor - Main class that orchestrates the extraction process
- Browser - Abstract interface for making web requests
- Helper utilities for URL validation and JSON parsing
- Type definitions for structured data representation
Added robust error handling for:
- Invalid URLs
- Non-existent tracks
- JSON parsing errors
- Content extraction failures

Testing

All tests pass with 96% code coverage for the extractor module. Tests verify:

Extraction from valid URLs (both regular and embed formats)
Proper URL validation
Error handling for non-existent tracks

Example Usage

from spotify_scraper.browsers.requests_browser import RequestsBrowser
from spotify_scraper.extractors.track import TrackExtractor

# Create a browser instance
browser = RequestsBrowser()

# Create a track extractor
extractor = TrackExtractor(browser)

# Extract track data
track_data = extractor.extract("https://open.spotify.com/track/4u7EnebtmKWzUH433cf5Qv")

# Access extracted data
print(f"Track: {track_data.name}")
print(f"Artist: {track_data.artists[0].name}")
print(f"Preview URL: {track_data.preview_url}")

# Get synchronized lyrics if available
if track_data.lyrics:
    for line in track_data.lyrics:
        print(f"{line.start_time_ms}ms: {line.text}")

Fixes #18.
