Update 3D structure viewer

Our current viewer (materia) is not ideal for viewing large (>10k atoms) structures and complex topologies. In order to support highly complex structures we would want to experiment with other viewers, especially nglviewer. This first version will only be enabled for structures with a topology attached to them: e.g. MD, MOFs from dinga and the systems with automatic topology created by matid.

• Add new API endpoint that can be used to load a single run.system.atoms through in a specified format (e.g. xyz, cif, etc.)
• Add nglviewer dependency
• Enable loading of structure into the viewer
• Create a new viewer component that use NGL. This should be a composition of a basic viewer component and a specialized component for NGL.
• Ability to visualize different parts of the topology. Should be something similar to what materia currently does:
  • Groups: other atoms transparent, focus on group atoms
  • Molecule / monomer groups: other atoms hidden, focus on group atoms
  • Molecules / Monomers: other atoms hidden, focus on molecule / monomer
  • Full system: everything visible, focus on system
  • Ability to load additional systems directly from the topology (e.g. conventional cells)
• The new viewer should implement the following controls:
  • Ability to turn bonds on/off.
  • Ability to turn cell on/off.
  • Ability to turn lattice parameters on/off.
  • Ability to reset view.
  • Ability to wrap atoms to cell.
  • Zoom, pan.
  • Enlarged view.
• Correct initial/reset view:
  • Systems with 3 lattice vectors: A pointing to right, C pointing top, slight rotation.
  • Systems with 2 lattice vectors: A pointing right, B pointing back, slight rotation.
  • Systems with 1 lattice vectors: A pointing right, slight rotation.
  • Systems with 0 lattice vectors: Slight rotation.
