Fix Docu time.rst - GetSystemTimePreciseAsFileTime() and monotonic() clock

[dbstf]

Documentation

Fix Typo: On Windows, the .time function now uses GetSystemTimePreciseAsFileTime() [--> 1 microsecond resolution] instead of GetSystemTimeAsFileTime() [--> 15.625 millisecond resolution].

Clarification: On Windows The .monotonic functions now use the same clock as the .perf_counter functions, not vice versa.
The .perf_counter functions previously already used QueryPerformanceCounter() + QueryPerformanceFrequency() [--> 1 microsecond resolution], whereas the .monotonic functions previously used GetTickCount64() [--> 15.625 millisecond resolution].
