Add/remove handles after creating the slider

[Tlepel]

Summary

It would be amazing if this library would also support dynamically adding/removing sliders.

Context

In my use-case it would be a great addition, my current workaround would be to destroy the slider instance and create a new one in its place, with the added/removed slider included in the config. However, that feels like a workaround that has a bigger (although not huge) impact on performace compared to a native API to achieve the same thing

How it would work

• The exposed API would have a method addHandle(connectionOption? = false) that allows you to add a handle to the end of the slider and set the connect option for the section between this new handle and the previous last handle.
• The exposed API would have a method removeHandle(handleNumber?: number, connectionOption?: boolean) that allows you to remove a handle (or the last one if no handle number is provided) and which sets the connectionOption for the 2 sections that were merged into 1

For your use case, are you looking to add/remove an arbitrary number of handles, or are you toggling between states?

[Tlepel]

It's a semi-arbitrary number, with a minimum of 1 and a maximum of 4 handles.
