[RealPOV.KoikatsuSunshine.dll] Feature improvements

[allrobot]

I hope to add the ability to modify the camera position for first-person view, such as making changes to the camera's XYZ coordinates. For reference, I am looking at the KK_PovX or HS2_PovX plugins written by FairBear. FairBear's PovX plugin provides support for settings related to the first-person view camera, which is quite convenient and offers a comfortable field of view.

If manually setting xyz is too cumbersome, you can use the Pov function of the ksPlug plugin created by Katarsys. By holding down the right mouse button and dragging, the camera can be moved along the xy-axis. When holding down the middle mouse button and dragging, the camera can be moved along the z-axis. Additionally, zooming in and out of the field of view can be done by scrolling the middle mouse button. The camera movements and zooming can all be controlled with a single mouse.

I also hope to expand the "Hide Head" option to include hiding the head and neck, as the neck slightly obstructs a small portion of the field of view.
