Returns a list of non-reduced dimensions in an un-normalized multi-slice.

@param {MultiSlice} slice - input slice
@returns {NonNegativeIntegerArray} list of non-reduced dimensions

@example
var MultiSlice = require( '@stdlib/slice/multi' );
var Slice = require( '@stdlib/slice/ctor' );

var s = new MultiSlice( 1, null, 2, void 0, new Slice( 0, 10, 1 ) );
// returns <MultiSlice>

var indices = nonreducedDimensions( s );
// returns [ 1, 3, 4 ]
