WebScraper class

High-level web scraper that combines HTML fetching and data parsing.

This class provides a simplified interface for web scraping by combining the Scraper (for fetching HTML) and WebParser (for extracting data) into a single, easy-to-use API.

Example usage:

final scraper = WebScraper();
final configMap = {
  'example.com': [ScraperConfig(...)]
};

final data = await scraper.scrape(
  url: Uri.parse('https://example.com'),
  scraperConfigMap: configMap,
);
