CapsulProcess depends on Morphologist

[ylep]

On the capsul3 branch, CapsulProcess cannot be instantiated when Morphologist is missing:

axon/python/brainvisa/processing/capsul_process.py

Line 263 in eabfb8e

'python_modules': ['morphologist.capsul.toolbox_init'],

Removing this line fixes the issue, but I guess it probably breaks Morphologist (untested).

Right.
