Add posibility to reset size to it's initial state

[MerlijnKerklaan]

I could not find a way to reset the splitter to it's initial state. I think it would make a great addition to the angular split component to be able to reset it to it's initial state.

Hey there @MerlijnKerklaan - feel free to create a pull request that includes tests and I will look at merging it.

The main issue here is what is initial state? If user moved the gutter and you update your size property - does it mean the initial state changed? If for example a new size came from outside without user interaction - does it mean the initial state changed?
I am not sure this is a feature that can be integrated as it sounds very use case specific. More like something the component using the split should handle by changing the size to the so called initial size when appropriate.

@beeman your thoughts on the matter?

I think it's not something we should add to the main library, it seems to be relatively simple to implement, and doing it your own way allows you to pick where you want to store this (state/local storage/database, etc).

As inspiration, you can look at this example and tweak it so you keep the 'initial' state and allow the user to restore that.

Hope that helps.
