Update tiny_gltf.h to upstream

[Squareys]

Hi @mosra !

As discussed per gitter.

(Summary for others: the patches I applied downstream back then seem to be obsolete.)

Cheers, Jonathan.

One important thing: the commit message should contain upstream commit ID (or a link to it, ideally) ;)

Looking at https://codecov.io/gh/mosra/magnum-plugins/src/b16dac21cbc2cd9c7b3cb3a94742dfc7b3e83bb1/src/MagnumPlugins/TinyGltfImporter/TinyGltfImporter.cpp#L655, the URI image import doesn't seem to be tested at all, so can't be sure if the update breaks this code path or not.

EDIT: dang sorry wrong button, didn't want to close. For the record, the CIs were green before I closed by accident.

Thank you! Merged into master now :) For the record, with those modifications:

• tinygltf update as 29661ad, but had to merge a few more things upstream, so the commit is different
• embedded images test as 61afb91, but the code was crashing on images with embedded data URIs, fixed in 34f3adb
• test file cleanup in 5ee0a5f, but the original commit forgot to update the corresponding glb files and missed a few cases, i did an overall cleanup in the following commits
