Downloads cloud images from configured directories to some locations

One may read architecture documentation to know project's architecture.

Configuration

Create a TOML configuration file:

db_path tells where to store the sqlite database (default is ~/.cache/cid.sqlite).

Use [[sites]] to define a site as an array of sites from whom to download cloud images. Each site may have the following keys:

• name as a string to name the site,
• version_list as an array of versions to look for,
• base_url as a string that tells cloud-image-download the base url where to download images,
• after_version_url as an array of directories to be added after the version (from version_list), image_name_filter as a Regex string to filter only these image names to download,
• image_name_cleanse as an array of Regex string to filter out the images (the images to download should not match any of those strings),
• normalize is a string that will be used as a template to normalize the filename of the saved image. You can use {version}, {date} and {after_version} modifiers in this string to customize the image name after these variable.
• destination is a directory where to store the downloaded images.
• timeout stands for a global timeout for requests made to get the directory files and directories. It is not used when downloading the files.
