Implement a hook useStep(totalSteps, initialStep = 0) that manages the state of a step counter for a multi-step process.

The hook should:

• Accept the total number of steps and an optional initial step.
• Provide the current step.
• Provide methods to move to the next step, prev step, reset to initial step, and setStep(n) to jump to a specific step.
• Ensure step never goes below 0 or beyond totalSteps - 1.
• Provide helpers isFirst and isLast to check if the current step is at the boundaries.

Example

const stepper = useStep(5);
stepper.next(); 
console.log(stepper.step); // 1
stepper.setStep(4);
console.log(stepper.isLast()); // true
