Starts a new terraneo module

See merge request !508

As discussed in the last developer meeting it is time, in light of soon to
come extensions, to start with a separate terraneo module. This is intended
to house code specifically addressing the needs of running mantle convection
models with HyTeG.

This commit starts with the new module and relocates the
SphericalHarmonicsTool into it.

DG implementation

See merge request !502

Removed duplicate code in DG conv. tests, made 3D test a little less demanding by lowering max level.

* fixes in macro-boundary detection
* 3D VolumeDoF PackInfo (direct only)
* DG 3D now also seems to converge with multiple macros

DG Poisson works on single macro-cell with hom. Dirichlet BCs. Penalty parameters can now be set from HyTeG.
