LSWT corrections to the classical energy and ordered moment

[Hao-Phys]

We have integrated LSWT corrections into the classical energy and ordered moment for both :SUN and :dipole modes. The numerical integrations are performed using HCubature.jl.

However, we have encountered an issue. When attempting to report the classical energy during correction calculations, the energy_per_site(swt.sys) function yields nonsensical results. This discrepancy is likely attributed to the rotation of all interactions. Shall we explore potential solutions to address this problem?

Yes, the plan is to undo the rotations in the swt.sys and store them in a new set.interactions field. I can do it today.
