v1.2.0 - Update interface

Main changes

Structure and transfer interfaces have been updated to use all DOFs, and a corresponding test case (van Zyl's T-tail) has been added.
Geometry variables name have been updated to follow new MPhys convention.

Note that the pipeline will fail because TACS is not built on the Docker image (see #1).
