This package integrates `denote'
(https://protesilaos.com/emacs/denote) with the Universal Sidecar
(https://git.sr.ht/~swflint/emacs-universal-sidecar).  As of now,
it provides only one section, a backlinks section to mimic that of
`org-roam'.

The backlinks section, `denote-sections-backlinks-section' may be
used as any other, simply add it to `universal-sidecar-sections',
it has no present customization.
