Does not support Arch Distributions

[MaKaNu]

While my arch installation is a modern systemd distribution, this package fails to parse my /etc/os-release.

Here is the content of my /etc/os-release:

NAME="Arch Linux"
PRETTY_NAME="Arch Linux"
ID=arch
BUILD_ID=rolling
ANSI_COLOR="38;2;23;147;209"
HOME_URL="https://archlinux.org/"
DOCUMENTATION_URL="https://wiki.archlinux.org/"
SUPPORT_URL="https://bbs.archlinux.org/"
BUG_REPORT_URL="https://gitlab.archlinux.org/groups/archlinux/-/issues"
PRIVACY_POLICY_URL="https://terms.archlinux.org/docs/privacy-policy/"
LOGO=archlinux-logo

Based on my tests it seems that the grammar expects a newline or EOF, which arch does not provide:

arpeggio.NoMatch: Expected '\n' or EOF at position /etc/os-release:(11, 15) => '=archlinux*-logo '.

But also adding a newline causes PARSER.parse_file(path) to fail with this error.
