Compile error on VRCLV V2 or older

[JLChnToZ]

Since VRCLightVolumes V3 isn't fully released, and as good practice we should stick on last stable version.
But doing so will will causes U# don't compile.

Here is the comsole log:

[UdonSharp] Packages/at.pimaker.ltcgi/LightVolumes/LV_LTCGI_Adapter.cs(471,7): Script with U# program asset referencing it must have an UdonSharpBehaviour definition; scripts without UdonSharpBehaviour definitions should not have an associated UdonSharpProgramAsset

I think the proper fix is to leave an empty U# class when VRCLightVolumes version doesn't fulfill, instead of fully carve out.

Does this actually cause any issues? I thought it just prints the log message.

Unfortunately no, this error will prevents uploading and testing the world.

Hmm ok, I'll fix it up.
