Iterate With Range
Generate sequences of integers using range parameters and loops.

Problem statement
Create a function iterate_with_range(start, stop, step=1) that returns a list of integers produced by iterating from start to stop using step, similar to Python's built-in range behavior. If step is zero, return an empty list instead of raising an exception. Use a loop to build the resulting list.
Task
Implement a function that returns the list of integers produced by Python's range(start, stop, step), handling a zero step gracefully.
Examples
Input format
A function call iterate_with_range(start, stop, step) where start and stop are integers and step is an integer (optional, defaults to 1).
Output format
Return a list of integers generated by stepping from start to stop using step. If step is 0, return an empty list.
Constraints
-10**9 <= start, stop <= 10**9, step is any integer. The resulting list length will be reasonable for typical inputs in exercises.
Samples
Sample 1
Input
iterate_with_range(5, 0, -2)
Output
[5, 3, 1]
Start at 5, step -2, stop before reaching 0.
