v2.0.0

High-performance responsive/progressive images for SvelteKit.

v2 has landed, and it's more optimised than ever! 🥳

First, a little background. v1 was originally developed to address issues with vite-imagetools, like how:

• inline directives are merged with default directives, instead of overriding them as expected;
• there's no easy way to create a <picture> tag;
• and there's no easy way to generate a base64 LQIP.

Fixing these required a tonne of patching. However, with the v5 release of imagetools (and the merge of this PR), svelte-img can be refactored to work the right way. Benefits include:

• handling more work at build step;
• leading to faster component rendering;
• and a much smaller payload (build size).

So please migrate.

BREAKING CHANGES:

1. ?run is deprecated; replace with ?as=run when importing images.
2. run default directives are defined using the runDefaultDirectives key now.
3. ?lqip={number} is deprecated; replace with ?as=run:{number}.
4. ?width={number} and ?height={number} are deprecated; use ?w={number} and ?h={number} instead.
5. Exposed CSS vars for FxReveal have changed.
6. If you're using svelte-img with an external image API, the src meta data structure has changed; it is now in parity with imagetools' native ?as=picture output format.
