iwd network configuration lives in this directory

See also `../../../etc/iwd/main.conf` especially in standalone iwd without
NetworkManager.

Notes:

- `git commit`ing the same SSID with different capitalisations breaks Windows
  and more common macOS setups due to their filesystems being
  case-insensitive.
- `Settings.AutoConnect=true` is unnecessary as it defaults to true according
  to `man iwd.network`.
- `IPv6.Enabled=true` defauls to true being also unnecessary.
- `private-home-sample.psk` has a comment on MAC address override and sends
  hostname with IPv4 DHCP. `private-cafe-sample.psk` always randomizes MAC
  address and doesn't send hostname.
- The `.open` networks always randomize MAC address too. If a network is
  private and needs MAC address for captive portal override or something,
  `private-home-sample.psk` should be adjusted from.
