Add sixDOFRigidBody Module

[joaogvcarneiro]

Describe your use case
This issue adds a new type of dynamicObject called dynamicEngine. An instance of dynamicEngine called sixDOFRigidBody is also added. It is a simplified version of the spacecraft module, with simple Newtonian and Eulerian mechanics. It leverages the kinematicsEngine and associated modules to manage the equations of motion in a frame-agnostic way.

Describe alternatives solutions you've considered
N/A.

Additional context
This is the first instance of the dynamics architecture in the works.
