Improve/create "API"

• Be able to call fixWhitespace with input lines, in addition to the ability of using it as a template tag. (This would likely involve having a new, separate, function.)
• Have a way of controlling what fixWhitespace does (e.g., don't remove trailing newlines).

I've seen a few libraries/demos do something like this:

const createWhitespaceFixer = require('fix-whitespace')
const fixWS = createWhitespaceFixer({ /* ..opts.. */ })

console.log(fixWS`
  Lorem ipsum! Magic!
  Additional lines!
  ${"Embeds!\n".repeat(5)}
  ..And other general usage of fixWS, blah, blah.
`)

edit: This would, of course, be a major version bump.

Very, very relevant:

A tiny library that fixes whitespace in JavaScript template strings.

I'd rather not go overboard. This is still a nice idea for some future time, though.

fixWhitespace is a tag function; it can technically be called with arbitrary input like this:

fixWS([input])

so, yay?
