Request for GPU Support for elastic Hessian in SPECFEM2D

[zhangchang271]

I encountered the following issue while using SPECFEM2D:

Sorry, approximate elastic Hessian kernels not yet fully implemented for GPU simulations!

I would like to use Hessian1 on GPU, which theoretically should not require adjoint wavefield computation. Is there a way to bypass this restriction and enable Hessian1 on GPU? Any temporary workarounds or suggestions would be greatly appreciated. Thank you!
