[Feature Request] support root dir for taxonomy output

[GlenDC]

Version: zola 0.15.3

I use taxonomy only for the blog section of my zola-generated website, which is found under /blog.
Currently I started to use taxonomis but sadly the generated output paths are generated as /<taxonomy> rather than /blog/<taxonomy>.

I don't think this is currently possible. It's not really a blocker or harmfull, but at the same time it doesn't really make sense to have these taxonomies as a root page if they only are used for one section of my website (the blog).

I do not mind to contribute in code, but I would require a bit of help and introduction to the codebase.

Let's see if other people want that.

After a night of sleep I decided for an intermediate solution I now declare these taxonomies as blog_authors instead of authors (as an example). This way I get a slug of /blog-authors, so at least the connection with /blog is already more clear :)

I could find this useful for organising collections of articles in a site that has a blog as well, where the articles might be linked together in collection after the fact rather than being a planned series in its own section which is I belive the currently recommended way of doing it.
