[ENHANCEMENT] Use current versions of tiny_object_loader and stb_image_write

[orgarten]

Describe the enhancement
Use the current version of

• tiny_object_loader and
• stb_write_image

in order to be up-to-date. I was just trying to fix compiler warnings in both files included with blazeRT but first, we should try to use up-to-date versions.

Unfortunately, updating the dependencies does not fix warnings.
