[Feature Request] Remove space before digits or replace with '-' when saving multiple frames as png.

[agaertner]

Just a very small thing. When saving an animation per frame into multiple pngs the enumeration is suffixed with a leading space.

It is prone to be accidentally removed when referencing in LaTeX or other software where extensions are omitted.

This is how one inserts 46 frames (react-page-frame <00-45>.png) as an animation into a PDF using LaTeX

\usepackage{animate}
\animategraphics[controls,loop,autoplay,poster=15,width=\linewidth]{12}{./img/react-page-anim/react-page-frame }{00}{45}

Notice the path ending with a space because of the file names containing a space (eg. react-page-frame 01.png). I would rather have (react-page-frame01.png) or (react-page-frame-01.png) than a space between name and digits because of editors wrapping its contents due to split screen.
