Starting to add networking helpers in archinstall. First up is archinstall.getHwAddr(ifname) which returns the mac of a interface name. second is archinstall.list_interfaces() which lists all the local MAC addresses and which interface it is bound to. Also starting to add the unattended installer back step by step. Currently with one MAC profile. The MAC profile filtering/detection has also been added in archinstall.list_profiles() - it will filter out all MAC address-specific profiles when called, unless a MAC matches a profile or filter_irrelevant_macs=False is given.
