Remove reference to dist/ from readme.md

[DanielHeath]

Now that the dist folder isn't available, links from readme.md do not resolve.

Annoyingly, there's no NPM package for the WADO loader and no dist package for this loader.

I've dug up the last dist/ release to use for now.

Oh, that's not good. I guess that fell through the cracks when we stopped including build artifacts in the git repository. Thanks for pointing that out!

There is definitely an NPM package for the WADO Image Loader though. What issues are you having with it?

https://www.npmjs.com/package/cornerstone-wado-image-loader
https://www.npmjs.com/package/cornerstone-web-image-loader

I've updated the readme to point to unpkg. You can grab the bundle and minified bundle from there. As @swederik pointed out, we publish npm packages for both of these image loaders.
