Misleading OpenMVG errors

Please change the error message here when you get a chance:

OpenSplat/openmvg.cpp

Line 243 in 86d2500

throw std::runtime_error("No project files found, please check the file path for sfm_data.json or sfm_data.bin");

This looks like it might have been copy-pasted and not changed, and has been very confusing lol

Thanks for the report @quinn-r88 ! Would you be interested in opening a PR? 🙏

Sure, I'll open one when I get a chance!
