Function everyNth

Returns true for every _n_th call, eg 2 for every second call.

If nth is 1, returns true for everything. 0 will be false for everything.

Usage:

const tenth = everyNth(10);
window.addEventListener(`pointermove`, evt => {
 if (!tenth(evt)) return; // Filter out
 // Continue processing, it is the 10th thing.

});

Alternative:

window.addEventListener(`pointermove`, everyNth(10, evt => {
 // Do something with tenth item...
});
