stb_image might not be thread safe

[giordi91]

I am currently hitting what it looks like some kind of race condition inside stbi_load. basically at random a deep assertion gets fired inside stbi_load, I bypassed soil and used the latest stb_image.h file and the problem looks like is gone. might be worth to update the implementation? also right now it is just an header file, should not be much of an issue?
