Confusion between reset! and setstate!

[klowrey]

lyceummujoco exposes setstate!(env, s) while lyceum base has a reset!(env, s) function. Their functionality seems to be generally the same: put the sim in a particular state s.

notably, LyceumAI's mppi function uses reset!(env, s) to reset the environment to a particular state; if length(s) != length(env.sim.initstate) there are problems. In this case setstate and reset functionally are the same.

If they are always the same, we should get rid of one of them.
