Resolves slice strides for a provided normalized multi-slice object.

@private
@param {MultiSlice} slice - normalized multi-slice object
@param {IntegerArray} strides - array strides
@param {NonNegativeIntegerArray} rdims - indices of non-reduced dimensions
@returns {IntegerArray} slice strides

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

var s = new MultiSlice( new Slice( 2, 3, 1 ), new Slice( 10, null, -2 ) );
// returns <MultiSlice>

var strides = slice2strides( s, [ 8, 2 ], [ 1 ] );
// returns [ -4 ]
