Converting multiple files

To convert multiple files, we recommend sticking to bash:

# For each of our input files
# DEV: We use `&` and `wait` to generate images in parallel
for filepath in *.tex; do
  # Generate a corresponding output file (e.g. foo.tex -> foo.tex.png)
  katex-screenshot "$filepath" "$filepath.png" &
done
wait
