Compability with CUDA 5.2

[lpawela]

CUDA.jl 5.2 enforces cuTENSOR 2. Consider the following compat section:

CUDA = "5.2"
DocStringExtensions = "0.9.3"
LowRankApprox = "0.5.5"
MKL = "0.4.2"
Memoization = "0.2.1"
SparseArrays = "1.9"
TensorCast = "0.4"
TensorOperations = "4"

This results in the following error (SpinGlassTensors is my package which has this problem)

Hi @lpawela , I think for now the only way to solve that is to not update CUDA to v5.2 yet. Sadly, cuTENSOR v2 is very breaking in comparison with v1, and while I have put in some effort to update: see #160 , I don't think I am ready to merge that yet, as I have not yet ported over the implementations for StridedViews. If you have some time to look into that further, I'd be very happy to assist, but I have some other projects running at the moment and have little time to immediately fix this.
It is however definitely on my to-do list, so I am definitely planning on fixing this.

@lkdvos just FYI why this might be important JuliaGPU/CUDA.jl#2171

Thanks for linking that. I had a quick glance, and it seems like this is the same bug that prompted the initial work on the update, so I'll bump the priority a bit. The annoying thing is that cuTENSOR 2 also requires Julia v1.8, so then we'd have to drop support for Julia 1.6 as I don't see having the time to maintain both versions. I'll keep you posted here if I make some progress.

This should be fixed as of version v5
