Subject: [PATCH] example: lottieviewer - fixed frame no

There is a problem (issue #527) with totalFrame() in rlottie.
As lottieviewer didn't showed the actual frame number, but calculated it from
progress, it camouflaged the problem. Now the actual frame number and the
total number of frames are displayed.
