Slow startup time when WAS nodes and REMBG installed

[fofr]

With was-node-suite, rembg and tinyterraNodes, this custom node takes ~40-50s to start, because of something to do with rembg.

With rembg:

1.6 seconds: /src/ComfyUI/custom_nodes/ComfyUI_InstantID
1.8 seconds: /src/ComfyUI/custom_nodes/was-node-suite-comfyui
54.0 seconds: /src/ComfyUI/custom_nodes/ComfyUI_tinyterraNodes

Without rembg:

0.0 seconds: /src/ComfyUI/custom_nodes/ComfyUI_tinyterraNodes
1.4 seconds: /src/ComfyUI/custom_nodes/ComfyUI_InstantID
1.5 seconds: /src/ComfyUI/custom_nodes/was-node-suite-comfyui

I'm not sure what the exact cause is here. This is with rembg already installed, and the install option set to False.

Moving from rembg import remove to the point of use, rather than at startup time seems to resolve the immediate issue: https://github.com/TinyTerra/ComfyUI_tinyterraNodes/compare/main...fofr:ComfyUI_tinyterraNodes:main

(Not raising a PR as this is not properly tested)

Thanks for pointing this out, and the example. I modified your change slightly to reraise the error with the extra information, instead of outputting from the node.

I can confirm this works 🙏
