The Sphinx build system for PDF is too complex and generate lots of ancillary files, including one PDF file for each image. So, at the end, the main latex dir has 156 pdf files, instead of the 71 ones that would match each generated book. That's confusing and it makes harder to identify when something didn't work. So, instead, let's move the final PDF output(s) to a separate dir. This way, the latex/ dir will have the temporary and the final *.tex files, while the final pdf files that built ok will be under the pdf/ directory.
