write tng files with velocities from mdrun
It would be great if we could write velocities from mdrun to a tng file directly. Right now we still need to store a trr file and then convert afterwards to a tng file.
Write forces and velocities to compressed TNG.
If there is no uncompressed coordinate output write forces
and velocities to the TNG file with compressed coordinate
output. If there is uncompressed coordinate output to a
TNG file forces and velocities will be written to it.
Use a greatest common divisor to set the frequency of some TNG
data output to ensure lambdas and box shape are written at least
as often as anything else.
