Using pyxrt with numpy v2.0.0 results in all bytes being read as 1.

Minimal reproduction script below. Uses xclbin file available here: https://gitlab.com/ska-telescope/low-cbf/ska-low-cbf-fw-cnic/-/packages/26156556 but I think any xclbin file or different Alveo card is likely to produce the same result.
