Slot for navigation (bullets)

[josegus]

Docs need to be improved, inspecting the component with devtools shows a "bullet" prop for VueGlide, but docs says nothing about this prop.

A slot for bullet navigation needs to be added.

I agree, I had to

`

<li v-for="(product, index) in products" :class="{ active: index === active }" @click="jump(index)" :key="index"

`
