scully-plugin-lazy-load-picture-tag

I wrote this as an :paperclip: angular-paperclip :paperclip: experiment from the talk by Misko Hevery (@mhevery) from the Keynote in NGCONF 2019

It is a lazy effort to lazy load images that lies int the <picture> tags. I am not sure why, since the srcset probably does that for you, but lighthouse stills complains about it. And instead of replacing all the possible tags in the code, I chose to lazy-load it using the adaptation for lazyload package that does the img tag instead.

You can specify the placeholder image when lazyloading the img, which is a nice touch for mobile slow 3g/4g :smile:
