Coding - Cast RWGltf_GltfRootElement to int for array size/subscript

macOS Clang reports value-not-implicitly-convertible-to-unsigned-long
for the static THE_ROOT_NAMES array size and the return subscript;
wrap the enum class value with static_cast<int>() at three sites
(RWGltf_GltfRootElement.hxx array declaration and subscript,
RWGltf_GltfJsonParser.hxx member array size).

The secondary ParseStream errors in RWGltf_CafReader are a downstream
instantiation failure that resolves once the parser header compiles.
