[BUG]: Does not support shaderpacks using geometry shader on terrain

[GeForceLegend]

Before creating an issue, please make sure you have checked the following:

• This issue does not appear without Chunks Fade In installed.
• All my mods (not only Chunks Fade In) are up-to-date.
• Similar issue had not already been reported before in the issue tracker.

What happened?

Using any shaderpack that uses geometry shader for terrain, the whole chunk will just be the fog color.

Renderdoc capture shows this mod only patch code to vertex and fragment shader, in geometry shader there is only fallback initialzation patched by Iris, which lets cfi_FadeFactor always be 0.0 when passed to fragment, and let the fog fade code always use 100% fog color.

Steps to reproduce

Launching with Sodium, Iris, and this mod;
Loading any shaderpack with geometry terrain shader. For example, SEUS_PTGI_GFME or Sundial Lite

Disabling this mod in the settings menu also breaks shader compilation, so Minecraft has to be restarted.

@Derjyn Can you send the logs, please?

Hi! As I remember I've made support for tesselation and geometry shaders some time ago, can you try now?

[GeForceLegend]

Is there any need for manually adapt for being compatible with cfi? I can see there is some cfi functions for color fade in but they seems never actually getting used in chunksfadein-fabric-3.0.21-26.1 with Sundial Lite's terrain fragment shader.

Anyway, I can see fade factor is correctly passed if there is geometry shader now. Even if there is no color fade in effect on some shaders, it's much better than the appearance when I submit issue: All terrain is using full fog color if uses geometry shader.
