Residual value prediction didn't help with stability (it's crimson-wish)

Also not a big help via the other approx KL formulation. W&B here. Though, it's slightly more stable?

We'll see how this run finishes converging.

It could be good to make things like this configurable in a branch and learning how these implementation details transfer to RLHF.

imo, residual clipping seems beneficial to prevent policy loss spiking reported in #101 . It's probably coming from instability in value estimation.

Yeah, I'm running residual clipping example(s), we'll see. At least it'll be good to have the option to try both.
