VMasonry, possible?

[legowhales]

Hey,

How easy would it be to implement a VMasonry component for svelte?
I see your are refactoring a few things about VGrid (react), maybe we could benefit this for a Masonry layout?

Awesome package btw!

I'm planning to create a similar component in #281 , which will support masonry layout.

I think basically it's possible, since there are some prior arts in React community (e.g. FlashList, Masonic, React Virtuoso). And we can port it to Svelte also.
