display downloadable files

When making the notebook where I included the Downloader class, I noticed it was not possible to easily display the downloadable files. In this branch I have mad a class function that prints the info in a nice format - it collects it from the page, so it updates, when more data is added.

qim3d/io/_downloader.py
