Opt-out of base64 fallback

[Trott]

Hey, first of all, really nice library, great job!

Wouldn't it be a better way to have base64 fallback as an option? Then it would be open for extension and if someone needed other encoding or no slug at all they could just add it on top of the library.

I would benefit from "no-slug" option in my project but I see that the underlying slugify function is encapsulated. If there was an easy way to access it then it would also be much nicer.

I wonder if the fallback is Too Much Magic™ and should be removed in a breaking change.

Hey, created a PR above.

It's easier to add than to remove they say. Having it as an option will be a huge relief already!
