- Update criterion-measurement to version
  * Change `criterion_rdtsc` to return `mach_absolute_time` on macOS. This is a
    portable way of returning the number of CPU cycles that works on both Intel-
    and ARM-based Macs.
  * Change `criterion_gettime` to use `clock_gettime_nsec_np` instead of
    `mach_absolute_time` on macOS. While `mach_absolute_time` has nanosecond
    resolution on Intel-based Macs, this is not the case on ARM-based Macs, so
    the previous `mach_absolute_time`-based implementation would return incorrect
    timing results on Apple silicon.
    There are two minor consequences of this change:
  * `criterion-measurement` now only supports macOS 10.02 or later, as that is
    the first version to have `clock_gettime_nsec_np`. As macOS 10.02 was
    released in 2002, this is unlikely to affect users, but please speak up if
    this is a problem for you.
  * As `clock_gettime_nsec_np` does not require any special initialization
    code, `criterion_inittime` is now a no-op on macOS. If you manually invoke
    the `getTime` function in your code, however, it is still important that
    you `initializeTime` beforehand, as this is still required for the Windows
    implementation to work correctly.
