Error occurred while loading shaders

Hello SPlisHSPlasH developer.
Thank you for good library.

I got a following error when I execute splash command and choose json file.

This error seems to be caused because the shader files are not under /usr/bin/resources/shaders.
I think it is difficult to put those file under /usr/bin/resources/shaders with pip.

So, the solution is copy those files to /usr/bin/resources/

cd .venv/bin
sudo cp -r resources /usr/bin/

Could you change the path of the referenced directory to not system but inside package, so that user can install it and start using it right away?
