FBX headers data can't be retreived (made a merge request for that)

[flarive]

Hey !

Just submited a merge request to be able to easily retreive FBX headers data such as creator, app vendor, app name, app version, creation date, last update date...

Tell me if it seems to be ok for you :)
Hope you'll merge it in master !

Usage in my app :

void fbx_mesh_loader::get_metadata(const ofbx::IScene* scene)
{
    const ofbx::Headers* headers = scene->getHeaders();
    if (headers)
    {
        int fbxHeaderVersion = headers->fbxHeaderVersion;
        int fbxVersion = headers->fbxVersion;
        int encryptionType = headers->encryptionType;
        char* creator = headers->creator;
        char* creationTime = headers->creationTime;

        char* documentUrl = headers->documentUrl;
        char* srcDocumentUrl = headers->srcDocumentUrl;

        char* originalApplicationVendor = headers->originalApplicationVendor;
        char* originalApplicationName = headers->originalApplicationName;
        char* originalApplicationVersion = headers->originalApplicationVersion;
        char* originalDateTimeGMT = headers->originalDateTimeGMT;
        char* originalFilename = headers->originalFilename;
        char* originalApplicationActiveProject = headers->originalApplicationActiveProject;
        char* originalApplicationNativeFile = headers->originalApplicationNativeFile;

        char* lastSavedApplicationVendor = headers->lastSavedApplicationVendor;
        char* lastSavedApplicationName = headers->lastSavedApplicationName;
        char* lastSavedApplicationVersion = headers->lastSavedApplicationVersion;
        char* lastSavedDateTimeGMT = headers->lastSavedDateTimeGMT;
    }
}
