v8.14

- WiFi | From Debian Bookworm on, the crda package is not available anymore. Since Linux 4.15 it is also obsolete, as the kernel is able to load this data directly. It requires however the data stored in /lib/firmware, which is the case from Bullseye (or Buster backports) on. For these cases, we do not not pre-install the crda package anymore, and offer to have it removed on next DietPi update. Our tools are adjusted to check for the existence of a key crda file to know whether to apply the country code to its config file and show the related menu option or not. The only other case, where the country code plays a role, is the WiFi hotspot, to provide it via hostapd. If the WiFi hotspot is installed but crda is now, the country code can still be selected, but is installed to the hostapd config only and not to crda or the interface directly (iw reg set).
