Title: Make it possible to access 'next' filter in onMixStart

Related feature request: https://mixitup.kunkalabs.com/support/topic/new-state-for-onmixstart/

Reason: I'd like to perform additional action *before* animation starts, depending on the filter being choosen. Unfortunately, the state object holds old filter, not the new one.
