feat: add MicroData extractor for recipe parsing and integrate it int…

Support for EasyRecipe Format

I have implemented support for the "EasyRecipe" format, which is used by sites like cookingdivine.com.

Changes

Extractors

[NEW] src/extractors/microdata.rs

• Implemented MicroDataExtractor which uses itemprop selectors within a schema.org/Recipe container.
• Extracts:
  • Name
  • Description
  • Image
  • Author
  • Prep/Cook/Total times
  • Servings (recipeYield)
  • Course (recipeCategory)
  • Cuisine (recipeCuisine)
  • Diet (suitableForDiet)
  • Tags (keywords)
  • Ingredients (supports ingredients and recipeIngredient)
  • Instructions (supports recipeInstructions and instructions)
• Design Decision: Enforced itemscope and itemtype="http://schema.org/Recipe" container check to avoid false positives from other schema types on the page.

[MODIFY] src/extractors/mod.rs

• Registered MicroDataExtractor in the main extractor module.

[MODIFY] src/lib.rs

• Added MicroDataExtractor to the list of extractors in fetch_recipe_with_timeout, prioritizing it before HtmlClassExtractor.

Verification Results

Automated Tests

• Renamed tests/test_easyrecipe.rs to tests/test_microdata.rs and updated it to use MicroDataExtractor.
• Ran cargo test --test test_microdata which passed successfully.
