Overriding computed properties is deprecated

[courthead]

The img-lazy component has three properties (_loaded, _loading, and _src) that are set to computed properties…

_loaded: not('observer.hasIntersectionObserver'),
_loading: oneWay('observer.hasIntersectionObserver'),
_src: computed('width', 'height', 'src', function() {
  if ((isFastBoot && !get(this, 'lazyFastBoot')) ||
    (!isFastBoot && !get(this, 'observer.hasIntersectionObserver'))) {
    return get(this, 'src')
  }

  return placeholder(get(this, 'width'), get(this, 'height'))
}),

…but are later overridden…

set(this, '_loaded', true)
set(this, '_loading', false)
set(this, '_src', src)

Overriding computed properties is now deprecated in the latest version of Ember and results in tons of warnings in the console. There are some instructions on fixing it here: https://deprecations.emberjs.com/v3.x/#toc_computed-property-override

Hi, I'm not actively maintaining this addon as I'm not using it in any projects at the moment. I'd be happy to accept a PR though :)
