38
* Demuxes a stream producing N outputs streams that contains n_0 items in
39
* the first stream, n_1 items in the second, etc. and repeats. Number of
40
* items of each output stream is specified using the 'lengths' parameter
41
* like so [n_0, n_1, ..., n_N-1].
42
*
43
* Example:
44
* lengths = [2, 3, 4]
45
* input stream: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ...]
46
* output_streams: [0, 1, 9, 10, ...]
47
* [2, 3, 4, 11, ...]
48
* [5, 6, 7, 8, ...]
