Vue-slider-component: Vue 3 support

[callumacrae]

Hey! Are you aware that this library doesn't work with vue 3 and do you have plans to fix it?

I'm getting this error:

I believe this is because you can't extend Vue anymore, which is happening here: https://github.com/NightCatSama/vue-slider-component/blob/master/lib/vue-slider.tsx#L48

Let me know if there's anything I can do to help - although I'm completely unfamiliar with this library's code.

Sorry, it is not yet compatible with Vue3.

It will be compatible when the stable version of vue3 is released.

The next version with vue3 support has been released, but it's still in beta, if you find any bugs you can report back to me!

$ yarn add vue-slider-component@next
# npm install vue-slider-component@next --save
