Publish client library to npm

[webkonstantin]

It would be nice to be able to use remark client library directly instead of dropping script tags on the page

Something like this

const remark = require('remark')

remark.embed(node, options)
remark.counter(node, options)
remark.lastComments(node, options)

Yep, we'll do it after switching from iframe widget to iframe-less (#218 (comment)). Right now it's overengineering to try to extract things from current widget to the package and to the iframe widget.

I'm leaving this issue open as a reminder. Thanks.

Possible Requirements:

• pack code by widget with ability to lazy load the module out of the box
• provide all of the necessary methods for controlling the widgets
• pack file with API methods separately and expose API methods for outside use

Ideas:

• create wrappers for JS frameworks (for example remark42-react) for easier integration with them
• provide theme context which provides ability to modify theme of comments
• provide ability to replace components with user's own implementation
