Add way to inject a custom thumbnail image component (for lazy-loading)

[pxpeterxu]

Per title; we show a lot of images at a time, which would slow things down a fair bit if we loaded them upfront. Instead, we wanted to use something like react-lazyload to load them as the user scrolled them into view (similar to how Google Photos did it).

Thanks for the great library, by the way!

Below is a gif of how it looks in the examples section:

Thanks @pxpeterxu. Hopefully I can get some time before the end of the month to cut a new release including this change. In the meantime it'll be available in master.

Thanks for merging this, Ben! And again, kudos for maintaining a super-useful library. Given how popular Google Photos is these days, it makes sense having a UI everyone's familiar with
