[Python] Fix Event callback for ARM64 Apple Platform devices

[agners]

With the latest build, the macOS builds print the following error on various (presumably all) devices which report events:

2024-04-23 21:40:35.270 (Dummy-8) ERROR [root] 16 is not a valid Status

ValueError: 16 is not a valid Status

16 is not a valid status indeed, and cannot originate from the C++ SDK really.

In another, second build, the status was 208 on every callback.

It seems that not all data type work with Python CFFI on Arm64. Use size_t here instead.

nice!
