Soft Navigations support

[SuperOleg39]

Hello!

Looks like that Soft Navigations is not so far to get out of the experimental status.

Maybe you already have some integration plans?
Or we can discuss it here)

Hi Any advise on how to reset each metrics and calculate again during soft navigation? Can this be supported currently by perfume.js until chrome is done with its experiment?

Thanks
