Details:

Detection and segmentation are two separate problems: one is for separating
signal from noise and the other is for partitioning/segmenting the detections.
For example in some conditions (especially very crowded fields), it can be
useful to have separate kernels used for detection and segmentation.

But adding yet another option (and more later) to NoiseChisel to do something
like this will only make it more complicated. This issue came up in a recent
discussion with Aaron Watkins.

To enable easier management of NoiseChisel and more user flexibility in
detection and segmentation, it would thus be good to break NoiseChisel into
two progarms, one for detection (still called NoiseChisel), and another for
segmentation (maybe called "Segment" with executable name `astsegment').

This is also in line with the Gnuastro' design philosophy
<https://www.gnu.org/software/gnuastro/manual/html_node/Program-design-philosophy.html>.

I don't have time to do this right now, but if any thoughts or suggestions
come up, please share it here.
