jackson-core/0001-Remove-ch.randelshofer.fastdoubleparser.patch

From 36ca1db668b34577de7586f5788cd038415ebbfe Mon Sep 17 00:00:00 2001
From: Chris Kelley <ckelley@redhat.com>
Date: Mon, 19 Jun 2023 21:07:53 +0100
Subject: [PATCH] Remove ch.randelshofer.fastdoubleparser

It is not packaged in Fedora, and it is not enabled by default, so take
it out. We can add it back in if we wish to package it later.
