No such file or directory error when using shell escape and tex files in subdirectory

[derchr]

Hello,
I'm facing an issue where a temporary file cannot be written during the compilation process when shell-escape is enabled to use the minted package.
I suspect the issue comes from the fact, that some of my source files lie in a subdirectory of the root src directory and the file creation in the tmp directory fails as the subdirectory is not explicitly created before writing the file.

If this is the case, a simple call to the std::fs::create_dir_all function should be able to create the subdirectories before trying to write files into them.

I was actually able to fix the bug applying this patch:

Yes, I can create a pull request. However, I do not have the knowledge of the code base to evaluate if this is the right fix to do, it just seemed to work in my case.
