[RFC]: add @stdlib/iter/cunone

[kgryte]

Description

This RFC proposes adding the package @stdlib/iter/cunone, which cumulatively tests whether every iterated value is falsy. The function should be a transform iterator, continuing to iterate while source iterator values are available.

var array2iterator = require( '@stdlib/array/to-iterator' );

var arr = array2iterator( [ false, false, false, true, false ] );

var it = iterCuNone( arr );

var v = it.next().value;
// returns true

v = it.next().value;
// returns true

v = it.next().value;
// returns true

v = it.next().value;
// returns false

v = it.next().value;
// returns false

var bool = it.next().done;
// returns true

Hi @kgryte , could you please assign this issue to me?

[kgryte]

@ruthwikchikoti Yes, and I suggest you focus on addressing RFC before working on #1632. The README issue is less useful than adding this feature.
