Added comprehensive tests to verify PIL compatibility fixes:
1. Problematic process_output handling:
- Tests handling of process_output that returns wrong format
- Verifies fallback to original tensor works correctly
2. Crashing process_output handling:
- Tests handling of process_output that raises exceptions
- Verifies graceful error recovery
3. PIL compatibility verification:
- Tests actual PIL Image creation with our output
- Verifies correct image size (512x512) and mode (RGB)
- Simulates ComfyUI's image processing pipeline
4. Different VAE types:
- Tests both SD (4-channel) and SDXL (16-channel) latents
- Verifies correct output format for all VAE types
Also fixed .gitignore to allow test framework files while excluding
specific test data files.
All tests pass! ✅ PIL compatibility test passed with fixes
The fixes ensure our node always returns valid (B, 3, H, W) float32 tensors
that are compatible with PIL Image.fromarray().
