altitude map of extended depth of focus projection

[bsorre]

dear Robert,
this is a sticky note following our discussion at the NEUBIAS course.

it would be great if the "extended depth of focus projection" of CLIJ2 could output not only the "focused" image but also the "altitude" of the best focus. this would allow to process the image on the dapi channel for instance and then apply the best focus to other channels.

many many thanks!
Benoit
