Data Exchange - RWGltf_CafReader fails reading texture embedded into base64 bufferView

Blender generated glTF files with textures embedded in non-standard way - it creates a single base64-encoded Buffer which is referred with offset for both vertex data and image data.

At the same time, spec suggests that base64-encoded images should be stored within "uri". So that although Blender encoding follows general logic for encoding base64 data via buffer views, it is unclear if such encoding for images complies or violates specs.

Nevertheless, it is desired to handle such use case.
Currently, RWGltf_CafReader ignores texture data from such files without emitting any error message.
