We add support for recording multiple snapshots at given times using cubic Hermite interpolation.
The user specifies the times through
conf.a_snapshots
.
For the forward evolution, we carry the previous ptcl, such that the interpolation can be done in one step.
For the backward adjoint evolution, the interpolation has to be split into two steps.
