There is no particular change in this update that we require. However,
our previous version, 5.3.0, is nearly two years old, so it seems
prudent to pull in all the upstream fixes that have been made since
then.
New wrap file taken from https://wrapdb.mesonbuild.com/fmt and modified
to download from GitHub as per commit 99dde1aff8 ("Download patch
files from Github instead of wrapdb").
Among other changes, this adds spdlog::should_log(), which lets us
easily determine whether a log message will be printed so that we can
avoid extra computation when unnecessary.
