feature request: create cruft directory if it does not exist

[jessestricker]

First off, thank you for this awesome tool! ❤️

latexindent --silent --cruft='./.aux/_latexindent' --overwrite ./root.tex

When I invoke latexindent as above, and the cruft directory does not exist yet,
latexindent fails to format the file and prints this error message:

FATAL Could not find directory ./.aux/_latexindent
      Exiting, no indentation done.

I usually keep my LaTeX projects in Git and do not commit the .aux directory, so when somebody clones the repo they need to manually create the cruft directory before they can start formatting files.

Would it be possible to create the cruft directory and any missing parents when running latexindent?

Please leave this open, I'll close it once released (hopefully soon) :)

Thanks so much for your contribution!
