chempy, quantities need numpy<=2.3.5

[AgnieszkaZaba]

There is conflict with some dependencies.
Possible sources: numpy, chempy, quantities (chempy dependence)

My current setup:

• numpy 2.4.2
• chempy 0.10.1
• quantities 0.16.1

Works for numpy<=2.3.5

Upgrading quantities package to 0.16.4 fixes the problem.
