Customize footnotes rendering

[ariasuni]

Bug Report

Environment

Zola version: 0.22.1

Expected Behavior

Being able to do things like:

• custom footnotes links, e.g.: [note 1] so it’s easier to click on/more accessible with the mouse (my main concern with current footnotes links)
• chose custom layout, e.g. if you want the backlink to be before the note number/name
• chose to add a header before footnotes so you don’t have to copy-paste it each time
• fancy footnotes?

Current Behavior

No way to truly customize footnotes

Step to reproduce

n/a

I'm not really planning to allow customizing them more than the default and the bottom_footnotes options.
