Feature Request: Make library usable within browser

[carstenschwede]

It would be useful to have this library available directly within the browser. Has this been considered already? Are there any methods that can't be replicated in the browser?

Based on a quick skim I would imagine that replacing request and require with corresponding fetch calls might be sufficient. (Other option would be to rollup all require calls for the courier inclusions in one chunk)

I dug deeper and there are a couple of couriers that are being crawled with cheerio which probably can't be replicated in the browser because of likely CORS issues.
