`Array_gpu::operator=` does not allocate correctly

[stijnh]

On the current main branch, I feel that operator= of Array_gpu is not implemented correctly. It first sets this->ncells and then checks if this->ncells == 0 to allocate memory if required. However, this well never happens since ncells was just set beforehand:

rte-rrtmgp-cpp/include/Array.h

Line 377 in 129363e

else if (this->ncells == 0)

I will fix this in a PR once I understand the Array class better.

You are correct. I implemented the view option later and something seem to have gone wrong here. As said before. On the long term we are also open for other array classes if you have better alternatives.
