Iris & Oculus Flywheel Compat

TL;DR:

• Fix issues in PBR and Parallax Occlusion Mapping.
• Support Seus PTGI HRR 3, Shrimple, and UShader, etc.
• Includes Flywheel in the jar file, so you don't need to install it separately.

1.1.3

• Fix issue #146.
  • Fix issues in PBR. Normals and tangents of moving contraptions now are correct.
  • Support Parallax Occlusion Mapping.
• Fix issue #150.
  • Replace vertex v with vertex _flw_v to avoid conflict with existing variables.
• Include Flywheel in jar file.
  • Because some users don't use the Create mod and have trouble with the Flywheel installation, I decided to include it in the jar file.

New compatible shaders:

• Seus PTGI HRR 3
• Shrimple
• UShader

There are still many that have not been tested but may be compatible.
