Move from tinygltf to tiniergltf (#13)

Browse Source 
* Remove tinygltf

* Integrate tiniergltf

* Update build.yml to include jsoncpp

* Namespace target

* Undo noexcept removal, readd move constructor

* Remove debug throw

* Remove now obsolete build code

* Bump CMake minimum version to 3.12

* Fix oops

* Remove unnecessary install/export

* Remove tinygltf from Config.cmake.in

* Take inspiration from Minetest's FindJson.cmake

* Move tiniergltf to separate repo

* CI: Install git

* Bump tiniergltf version (obtain jsoncpp via FetchContent)

* Remove jsoncpp from build dependency list
