The multi-colony masks do not get generated when using MATLAB full installation

[janamach]

This might be a my-system-specific-bug, but I will report it here in case someone else experiences a similar problem.

When using MATLAB full installation and trying to use the multi-colony option, "geometry_multi_colony": gets set to true in prmtrs.json, but no mask png is generated and I get the following errors on master and other branches:

However, when I use MCR (instead of the full MATLAB installation), the mask gets properly generated and multi-colony tracking works as described.
