Ensure compliance with copyright for the OrthographicTrackballControls module

Description

The OrthographicTrackballControls found in the lib of the client application shows authors that are not part of the project.

I am not sure of the exact source for this version of the module but I found what appears to be a possible previous version here. This has the MIT License attached which contains the following line:

The MIT License (MIT)

...

The above copyright notice and this permission notice shall be included in all
copies or substantial portions of the Software.

...

I do not see the notices in the project. Also, I do not know if this project's GNU LESSER GENERAL PUBLIC LICENSE causes issues with the MIT license. From some quick reading, looks like GIMS has more restrictions with the GNU Lesser GPL licence but maybe fine withe the MIT licencsed component (except that you need to reproduce the license and copyright notice)

This issue is essential as part of my review for JOSS.
