Gromacs Wrapper around tng datatype.
This could in principle hold any GROMACS-specific requirements not yet implemented in or not relevant to the TNG library itself. However, for now we only use it to handle some shortcomings we have discovered, where the TNG API itself is a bit fragile and can end up overwriting data if called several times with the same frame number. The logic to determine the time per step was also a bit fragile. This is not critical, but since we anyway need a wrapper for ensuring unique frame numbers, we can also use it to store the time of the first step and use that to derive a slightly better/safer estimate of the time per step.
At some future point where we have a second-generation TNG API we should consider removing this again.
