[Feature Request] Better handling of variables in archive paths

[diamondsw]

The download-archive directive (or archive variable in a conf file - why are these named differently?) always fails if any variables are used in its path (for instance, if you want to keep archive db's in artist or manga folders when downloading from mangadex), as the folder is not created until after the first image is downloaded.

For instance, the following option will always fail for the first chapter since it looks for the DB path to exist before downloading, but once the first image is downloaded, the path now exists for all subsequent chapters. This means, however, that the command must be run twice to have everything in the archive.

--download-archive '~/Downloads/[{author[0]}] {manga}/archive.db'

Would it be possible to add a flag to create the path if it doesn't exist, utilizing any variables from the download session?

why are these named differently?

This feature was meant to more or less copy youtube-dl's --download-archive, and config file option names are usually just one word.

as the folder is not created until after the first image is downloaded.

Should be fixed with a96f9d2.
