Update ps5000aRapidBlockExample.py

This example program will randomly crash with access violations (0xC0000005). Have traced this to ctypes.byref() passing pointers with incorrect memory sizes on the indicated lines:
* 81-82 GetTimeBase2 expects returnedMaxSamples as * int32_t, was receiving byref(int16).
* 290-292 GetValuesTimeOffsetBulk64 expects Times as * int64_t, was receiving byref(int16).
