Add job forms for Segmentation and Caliban consumers

[elaubsch]

This PR adds segmentation and Caliban job forms. Because the requirements of each form are all different, they are added as individual files.

Segmentation Form
The job form for the segmentation consumer allows the user to input single channel images of nuclear or whole-cell label channels or a two channel image of nuclear and whole-cell label channels. The channels variable will be used by the segmentation consumer to bring up the nuclear and/or whole-cell models as determined by the channels entered in the form.

Caliban Form
The job form for the Caliban consumer does not have a channels form, because it expects single channel images.
