Fix url rewrites problem and removes url_path

• The attribute url_path, if exists, is removed from the imported products
• url_rewrite table: Writes non-redirects (redirect_type = 0) before redirects (redirect_type = 301) in url_rewrite, because Magento relies on this order when it creates canonical urls and such.

Added missing options

Added some options that were missing from the cli command and the rest api.

Support for Magento 2.4

Support for 20.6 price decimal format.

Fixed import of tier prices in M2.4

Fix XSD for multiple store views

The XSD that validates the product import XML did not allow multiple store views.

An option to have old category links removed

Guus Portegies asked for this option to have product-to-category links to be removed as well as added.

Setting $config->categoryStrategy = ImportConfig::CATEGORY_STRATEGY_SET will remove product-to-category links that are not named in the import.

Use responsively; the documentation explains when this is not a good idea.

Url suffix per website

Take into account that product and category url suffix may differ per website.

Url suffix per store view

Take into account that product and category url suffix may differ per store view.

• Bundled product option value, parent_product_id (since M2.2)

Magento 2.3 only added MSI, and did not change the existing product tables.
