Request: Add logic for handling Modifiers

[ll-r-magner]

No "issues", this is a great template to get started and save us Developers some time. However, the variant-selector component is coded to handle variant options very well and even renders options for modifiers however it does not handle the fact modifiers are not "available for sale" and also doesnt allow you to add any product to cart that has a modifier.

TLDR; Please add logic for handling modifiers within variant-selector component and add to cart functionality.

Thanks for the request @ll-r-magner 🙇

I'll bring this back to the team!
