[HCharaAdjustment][Enhancement] HCharaAdjustment should also support rotation.

[leoftm]

As the title suggests, I would like to request that HCharaAdjustment, which currently only supports movement, be added to support rotation (similar to the overall movement in vanilla).
I understand that changing the rotation may cause the animation to be corrupted, but I would still like to have rotation for fine-tuning.
