Symplectic integrators

[mateuszbaran]

We most likely need symplectic integrators for manifold HMC and manifold CNFs. See for example: https://doi.org/10.1080/00207160.2021.1966772 .

Interesting – I saw that paper, too; @ergyscokaj might be interested or at least take a look at what we do there.

We already have CG and RKMK integrators sort of figured out here so I hope implementing a moderate-order symplectic method won't be too difficult.
