When a mapped product is simple on WC but has variants in Odoo, a purple
"N variants" button appears in the Variants column. Clicking it:
1. Converts the WC product from simple to variable
2. Creates WC attributes and terms from Odoo attribute lines
3. Creates a WC variation for each Odoo variant with price/SKU/stock/tax/image
4. Creates woo.product.map records for each variation
