Constraint types without runtime overhead

These types are most useful in conjunction with static type checkers like mypy.

import teext as tx

a = tx.PositiveInt(5)  # OK

def f(x: tx.PositiveInt) -> None:
    print(x)

f(a)  # OK
f(7)  # works at runtime but mypy gives error

b = tx.PositiveInt(-3)  # AssertionError
