arrayChunks method
Returns an iterator over N elements of the iterator at a time.
The chunks do not overlap. If N does not divide the length of the iterator, then the last up to N-1 elements will
be omitted and can be retrieved from the .intoRemainder()
function of the iterator.
Implementation
@override
ArrayChunksRIterator<T> arrayChunks(int size) =>
ArrayChunksRIterator(this, size);
