IMAQdx Camera worker fails if Numpy >= 2.0

[mjdoris]

Hello, we encountered this issue yesterday. I was tempted to make the change, but instead decided to just downgrade numpy to something below 2.0. I looked at the dependencies in the toml project file and see it lists numpy>=1.15.1, which could create a situation where numpy 2.0 is installed and cause this error. I'm not sure if it would be better to add that numpy should also be < 2.0 in the dependencies, or change all instances of string_ to bytes_.
