Forward slash is valid url character but removed

Slugify is designed to support valid url characters. However if I pass in a forward slash:

slugify(`Something/Another thing`, { lower: true })

The result is:

somethinganother-thing

Where I would expect:

something/another-thing

This can of course be mitigated by changing the remove RegEx adding \/:

console.log(slugify(`Something/Another thing`, { lower: true, remove: /[^\w\s$*_+~.()'"!\-:@\/]+/g }));

But this is not a very elegant solution. Ideally there would be an ignore/exclude character feature?

console.log(slugify(`Something/Another thing`, { lower: true, exclude: '/' }));

This is perhaps more maintainable and understandable than passing in a remove regular expression.

function slugifyWithSlashes(myString) {
 return myString.split('/').map((val) => slugify(val)).join('/')
}

This is probably an over-engineered and inelegant solution, but I can’t tell so here it is anyway:

It would be a breaking change, but perhaps the strict option can be deprecated in favor of a mode setting that affects the defaults of things like the remove regex. slugify can ship with a strict mode and loose (or sloppy or whatever you want to call it) mode, but people could add their own and perhaps even ship them as separate packages, effectively being a plugin:

const slugify = require('slugify')
const slashesMode = require('slugify-plugin-slashes-mode')

slugify.addMode(slashesMode) 
slugify.mode = 'slashes'

// Or maybe `.use()` or `.useMode()` to do both of the above two lines at once?
