Slow Motion Physics Fix NVSE

During extreme slow motion (via sgtm console command or mods like QUIP that manipulate game time), physics objects can jitter erratically. This happens because the time step passed to the Havok physics engine becomes too small for the solver to handle accurately.

When you set sgtm 0.01, each frame's physics step shrinks to ~0.00016 seconds - far below what Havok was configured for. The solver loses precision and objects vibrate instead of moving smoothly.

This plugin accumulates those tiny timesteps until they reach a minimum threshold (0.008s), then runs physics with the accumulated time. The result is stable physics during slow motion without losing simulation accuracy.

Thanks to Wall for his help in cleaning up the code and identifying a more compatible solution than the sledgehammer I initially came up with.
