v1 Candidate (#8)

* Bump devDeps, microbundle, use TS strict mode

* Prettier all the things

* Tune eslint to speak Typescript

* Install husky

* Fix fallbackUtils errors

* Accept 'sizes', refactor LazyImageFull

Breaking:
LazyImageFull now only takes children as a function, not render.

Improvement:
Simplified LazyImageFull code in a bunch of places, such that
it only concerns itself with the observing and loading.

* Pass ref, use prop collection

* Refactor props collection

* Factor out initialState, consolidate ImageProps

* Update usage instructions

* Update stories

* Bump react-intersection-observer

* Update stories, handle refs

Refs make things more annoying, but at least there is no wrapper
now.

* Add experimental img.decode() support

* 1.0.0-rc.1

* 1.0.0-rc.2

 # Investigate
+
 - [ ] Auto sizes (if not handled already by browser behaviour)
 - [ ] cancel loading on componentWillUnmount
 
 # Later
+
 - [ ] abort loading if image leaves viewport and it has not loaded sufficiently
   - Likely a large change to how we do things
   - Possibly with using fetch and cancelling it
