Missing #include <cstdint> in ClockDelta.h causes build failure with GCC 15

[aneshlya]

Description

Building OpenMoonRay v3.6.0.1 fails with GCC 15 due to missing #include <cstdint> in ClockDelta.h. The uint64_t type is used without the necessary include.

Error

moonray/moonray_arras/mcrt_dataio/lib/share/util/ClockDelta.h:60:44: error: 'uint64_t' has not been declared

Environment

• GCC 15.2.1 on Arch Linux
• OpenMoonRay v3.6.0.1 (via AUR package)

Suggested Fix

Add #include <cstdint> to ClockDelta.h.

Notes

This worked in v2.40.0.1. The issue was introduced somewhere between v2.40.0.1 and v3.6.0.1.
