Add option for fetchpriority attribute within "image loading" area on image field formatter

Would it be better to add a selector with three options?

• Priority: high
• Priority: normal (no attribute added; default)
• Priority: low

I could see that, although I'm not sure of a regular use case for the fetchpriority to be low.

I think a common scenario would be where you have multiple items in a carousel where only one item would be visible until the visitor specifically selected it to show the next slide. Of course this would be completely implementation-specific, e.g. it could cause complications if the carousel automatically rotated.
