warning: 'sprintf' is deprecated

Hello! I was compiling vsgXchange on macos for the first time and got the following:

/Users/psi29a/Workspace/private/daggervsg/upstream/vsgXchange/src/stbi/stb_image_write.h:776:13: warning: 'sprintf' is deprecated: This function is provided for compatibility reasons only.
