Ability to create custom instances

[sjwalker189]

It would be nice to be able to create individual instances of slugify like the following:

import slugify from 'slugify'

const urlify = slugify.create({ /* options */ })

This would be useful in larger projects where there may be slightly different use cases that are used often. This would be more preferable than remembering the regex each time, or writing a custom wrapper.

That's a good idea 👍
