Add package.json / publish to npm

[strarsis]

It would be great if this gets a package.json added and
published to npm so it can be directly used with e.g. webpack.

Hi starsis,

I am not much of an npm person but please feel welcome to send a PR.

@strarsis maybe this might work https://www.npmjs.com/package/js-backgound-blend-mode

@idevsoftware 😜

@juanbrujo: Thanks! Nice fork. Though I can't create issues there. In TODO of readme is listed 'NPM module'. This can be marked as done because you already published it on npm.

[juanbrujo]

thanks, done!

[strarsis]

@juanbrujo: Could you also enable issues in that repository?

[juanbrujo]

done @strarsis !
