can destructure the require's load now

[kylegoetz]

I pulled the module's anonymous parser function into a named function and then referenced that inside the load function rather than using the $=this method. The latter breaks when you try

const {load} = require('rss-to-json')

but it works with the method I used. And since it's possible the user might only need to use load and never import parser or reader, I figured why not?

Also this varies in what it means depending on whether you're using strict mode or not (and if you use new by mistake), which just gives me the heebyjeebies :)

Because this technically changes the topology of the module by adding a new feature (but not breaking anything else), I bumped the version from 1.0.3 to 1.1.0 as per my understanding of semantic versioning.
