Feature/texturewriter stb

[WeirdRubberDuck]

• Update stb_image version
• Add a STB texture writer, that can save textures to disk (supported formats: jpg, jpeg, png, bmp, tga. HDR is left out for now, se comment)
• Add a test to the test suite, that already erxisted but not actually compiled

Used in OpenSpace PR: OpenSpace/OpenSpace#2912

Eek, I got those now too when doing a completely clean build. Will have to check out howto handle the duplicated dependency

I think this might have been fixed with the recent AssImp update. Not getting the linker errors anymore
