Synchronize the writing of several products from Python API.

It would be nice to have a way of using multiwriter from Python API without having to define a new application like AppImageListWriter in MAJA.

If we consider a flow like the following:

+----+     /--------\     +-----+     /----------------\     +---------+     /------------\     +----------+     /----------\     +-------+
| S1 | --> | to_xyz | --> | XYZ | --> | extractNormals | --> | Normals | --> | computeLIA | --> |   LIA    | --> | OrthoLIA | --> | S2LIA |
+----+     \--------/     +-----+     \----------------/     +---------+     \------------/     +----------+     \----------/     +-------+
                                                                               |
                                                                               |
                                                                               v
                                                                             +------------+     /----------\     +----------+
                                                                             |    Sin     | --> | OrthoSin | --> |  S2Sin   |
                                                                             +------------+     \----------/     +----------+

We don't have any way (as of v7.2) to plug extra applications on separate paths after an application that produces several images.

In an ideal world, we could write something like

otb.write_outputs(appOrthoLIA, appOrthoSin)
