LazyLoad only visible cells

[a-v-l]

depending on the cellAlign option.

So, if cellAlign: 'right' is chosen only lazy-load the images left to the index and if cellAlign: 'left' is chosen only load those to the right. For the default situation (cellAlign: 'center') the images to both sides are lazy-loaded. It's a small enhancement but it also only costs a couple bytes.

(Most of the 40 additions and 23 deletions come from running gulp uglify. Not sure if that's how it should be done…)

Thank you for this contribution! Like you said, this is a minor adjustment. It's a nice addition, but I don't know if it's significant enough to merge.

Add a 👍 reaction if you would like to see this PR merged.

There are a couple scenarios where I have used Flickity as a kind of forward-moving-only, linear slideshow — and an upcoming project that is going to be rather data hungry. Having Flickity lazyload with a simple option rocks — but I could see a "forward only lazyload" being even better in these occasions.

That said, I could see this being a stretch from a code standpoint.

Disappointed this isn't getting more 👍
