feat: use transform only transitions

[Djoow]

For now, in this project, transitions are reacting to any kind of changes. In some cases, if something change on burger hover for example, transitions are wrongly triggered.

This fix allows transitions to be triggered only on css transform property change, allowing external interactions on the burger (background color change, etc).

Thanks for the PR!

In a lot of cases, you'll want to do something like this:

<Hamburger toggle={toggle} toggled={toggled} color={toggled ? 'white' : 'black'} />

Previously this would animate nicely along with the other transitions, but this would break in your current approach.
