Please Support LocalRotationX,Y,Z,XY,XZ

[Difficulty-in-naming]

Currently, if we want to animate rotation around only one local axis (e.g., making a door swing open around its local Y-axis), we have a few options:
Tween localRotation (Quaternion): This requires calculating the target Quaternion based on the desired angle change around a specific axis. While powerful, it can be less intuitive for simple single-axis rotations compared to just specifying the target angle.

Hey! PrimeTween had this feature in the past, but I removed it after a deeper consideration.

The issue with rotations around axes is that they are not cumulative and can behave unpredictably. For example, rotation around one axis can modify absolute rotation values around other axes in a very unintuitive way. More info: #73 (reply in thread)

The best alternative you can use is Tween.EulerAngles/LocalEulerAngles, which requires you to specify the startValue explicitly to avoid any ambiguities.
