[Bug] Client attempts to classload Indium with Embeddium installed

[Partonetrain]

Describe the bug Embeddium natively integrates Sodium with Fabric Rendering API. Copycats+ expects Indium and Sodium and attempts to calll Indium classes even if it's not installed

To Reproduce Steps to reproduce the behavior:

1. Install Embeddium and Create Copycats+ (on Fabric)
2. Place copycat stone button (possibly more blocks)
3. Crash

Expected behavior No crash

Desktop (please complete the following information):

• Minecraft Version: 1.20.1
• Mod Loader Version: Fabric 0.15.11
• Mod Version: both 2.0.4 and 2.0.5

Theres a lot of issues between sodium and create so indium is almost a hard requirement for it to function properly and i believe create actually prompts you to install it

[hlysine]

This is a simple incompatibility where Embeddium registers a stub for Indium without providing Indium classes. We can probably switch back to using FRAPI classes if Embeddium is installed.
