HoyoToon Update

Hope everyone had a good holiday season! Starting off the new year with a new release!

HoyoToon V4.7.0

Added support for the Starry Sky shader feature.
- Similar to the Star Cloak feature in Genshin Impact but not exactly the same. This doesn't use the same textures as it and can be implemented on other characters if the correct textures are created.
Added support for the Height Light shader feature.
- This feature is the one used in the character view screen, the darkening of the characters lower legs.
Reimplemented the Dissolve shader feature.
- Removed the advanced/simple enum and instead uses the same logic as the ingame version. This is still more advanced than the Genshin Impact version as the features were created with a scripted animation system in mind.
Added a new parameter in the Face category for adjusting the softness of the face shadow. This works the same as the Genshin Impact face shadow softness.

Implemented a stencil system for the eyes similar to Star Rail's.
- This feature was funded by ZukuUzu.
- This feature cannot be used at the same time as the Nightsoul shader feature. The shader will show a warning if both are enabled.
- This feature requires you to seperate the eyes from the hair material and make it it's own material. There will be a FAQ post explaining the process. Don't worry, it's not hard.
Added the updated face_shadow textures to the resource folder.
Added a new parameter in the Face category for using the updated face_shadow textures as an extra AO map.
Improved the existing Custom AO system.
- The system now works better with the body/hair/dress/etc materials as it wont be so weirdly harsh.
- The system now lets users change what UV coordinates and sampler types are used for the AO map. The default values are UV0 and linear repeat.

Added support for the Aurora shader feature.
- This feature is what shows up on Shorekeeper, the pulsing light effect on her veil.

Rmoved old leftover functionality to maintain old prop information from raw models.
