Generate an MP4 animation from a sequence of frames. The demo writes
output/example/fortran/animation/animation.mp4.
save_animation also accepts a .txt filename to emit frames as ASCII renderings
delimited by === Frame N === headers. Replay them in the terminal with the
fortplot_play_ascii CLI app:
fpm run --target fortplot_play_ascii -- output.txt --fps 24 --loop
Pass fig= to FuncAnimation (or use set_figure) before saving. A missing
figure, callback or positive frame count returns a nonzero status. For a video
filename, zero status means that the requested video was produced and validated.
If encoding fails, diagnostic PNG frames may still be saved, but the video save
returns a nonzero status; the PNG fallback is not a successful MP4 save.
