Native units for Python

Python introduces two new builtins:

• intu — a unit-aware integer (a subclass of int)
• floatu — a unit-aware float (a subclass of float)

Together, these are called u-numbers.
They behave like normal numbers but carry units, and arithmetic automatically respects those units.
