feat: time vertex seeding

[felix-russo]

The AdaptiveGridTrackDensity is adapted to accommodate time vertex seeding. Unit tests are added.

In the unit tests, the analytical maximum and width of a 3D Gaussian along the z-axis is used, see Gaussian_Track_Density.pdf for a derivation.

sorry I did not take a second look yet. is this ready for a fresh second round @felix-russo ?

[felix-russo]

Yes, should be good to go @andiwand :)
