deprecate sapporo_light?

[rieder]

I don't know of any reason why sapporo_light should be preferred over sapporo2.
If there are none, I suggest deprecating sapporo_light in favour of sapporo2.

And perhaps sapporo2 could be updated to support Vulkan (which I think would increase the number of supported GPUs greatly), see treecode/sapporo2#5.

Sapporo_light has a number of deficiencies and from a ph4 standpoint, it only works properly with sapporo2. It still some issues, but it’s a basis for what we need, I think. Steve
