Subject: [PATCH 3/3] gnu: fulcrum: Update to 1.9.1.

From: Jean-Pierre De Jesus DIAZ <[email-masked]>
Date: Wed, 20 Sep 2023 14:39:33 +0200

* gnu/packages/finance.scm (fulcrum): Use the upstream origin instead of
  the Flowee's fork of it, updates and expands the synopsis and
  description.  Updates the package to 1.9.1 and build without any
  bundled libraries with the help of a patch.

* gnu/packages/patches/fulcrum-1.9.1-unbundled-libraries.patch: New
  patch.
