Custom Rules: `palette` not applied to custom fields

[Kikobeats]

Originally reported by Stefan Charsley.

Current Behavior

For custom rules with the palette option, even when the rule is set to type of image, no palette information is received.

Example:

$ curl https://api.microlink.io/?url=https://www.taratahi.ac.nz/news/fmg-taratahi-scholarship&palette=true&data.imageOverride.0.selector=.content-section+img.js-image&data.imageOverride.0.attr=data-bttrlazyloading-lg-src&data.imageOverride.0.type=image

returns (notice how the imageOverride property is just the url compared to the image property)

@Kikobeats is there any eta for this?

I'm not sure if it was a edge case or it was fixed, but looks it's working fine

Just I'm going to close this until we find an edge case again 👍
