[momshaddinury]

Description:

This PR fixes the axis usage in the zoomOut method to align with their intended behavior as described in the comments.

---

Changes Made:

1. Updated zoomOut to manipulate the negative z-axis (farther).

---

Updated Code:

  /// A helper method to perform a single [step] of a [relativeMove] on the
  /// negative y axis (farther)
  Future<void> zoomOut(String profileToken, [double step = 0.025]) async {
    loggy.debug('zoomOut');

    await zoom(profileToken, Vector1D(x: -step));
  }

---

Testing:

• Verified zoomIn moves closer along the positive z-axis.
• Verified zoomOut moves farther along the negative z-axis.

Thanks @momshaddinury, this PR helped me find a bug in the cli application I use for some testing. A new package will be released shortly.
