note that this has been unxz'd already.

truncate -s 6g FreeBSD-13.0-RC5-arm64-aarch64.raw	# enlarge
mdconfig -f FreeBSD-13.0-RC5-arm64-aarch64.raw		# make device
gpart recover md1					# fix up gpt
gpart resize -i 3 md1					# expand ufs partition
growfs md1p3						# grow ufs

Note that mdconfig may output a different md device than md1, use
that instead.
