Subject: [PATCH] normalize config file name for download to make it work on
Windows
Windows client name is derived from config file name when importing to WireGuard and it only accepts names satisfying /^[a-zA-Z0-9_=+.-]{1,32}$/.
For more information look at https://github.com/WireGuard/wireguard-windows/blob/af60ab229954519b8295bb3ef453231f4d3b9087/conf/name.go#L24.
