It might be nice to add support for ImplicitDifferentiation.jl or similar to make the reconstructed image differentiable with respect to the input image (and/or the hyper-parameters like λ).

@gaurav-arya worked out the algorithms for this in this paper (2022), section 2.2 (for ElasticNet regularization, which includes TV and Tikhonov as special cases), where he used it to co-design optics for CS reconstruction.

I would need to read on that.

Can @gaurav-arya help regarding the implementation?
