qdp will not compile under gcc-12 due to commit d823261

[RJHudspith]

Hello,

The most recent commit (d823261) cannot be compiled under gcc-12, whereas the previous version (qdp-1.46) was fine.

This problem is very easily fixed by adding an

#include <array>

to the top of include/qdp_map_obj_disk.h.

I gather in gcc-12 some include of array was removed requiring it now to be explicitly stated.

Best,
Jamie
