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.
@JSUYA Thanks for review. There were a problem in patch #529. Now works.
For a_cup_of_coffee.json, before patch 529 last frame is 71 (total: 72), after patch 72 (total: 73).
