About update numpy to 2.0

[albertandking]

Hi, Ed

1. numpy had released 2.0 at 20240617, ref: https://numpy.org/news/;
2. pybroker should consider update numpy 1.x to numpy 2.0
3. I have test numpy 2.0 in pybroker, we can just replace np.float_ to np.float64 in all source code;
4. then should set numba version great than 0.60.0, ref: https://numba.readthedocs.io/en/stable/release/0.60.0-notes.html
5. If you consider update it, I will pr to dev branch.
