Accept item index as an argument for formatter function

[mestaritonttu]

Currently the formatter function takes value and timestamp. In Chartist, there is a labelInterpolationFnc that takes value and index. This allows showing only certain label items like so:
return index % 2 === 0 ? value : null;
This is useful for getting stuff as minimal as possible on mobile.

No problem, I can provide the third argument as index
