Draft: Proposal for how to add compression parameters via the command line for #158
Allow to add compression parameters via the command line.
This allows to build a preset such as
ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"
PRESETS=('demo')
demo_config="/etc/mkinitcpio.conf"
demo_image="/tmp/initramfs-demo.img"
demo_options="--add-compression-parameter -10 --add-compression-parameter --fast"
