upgrade from v0.3 to v0.4

[marcraft2]

Lots of changes between these two versions.
You have the nginx/cerbot step to redo with freenom, to generate an ssl certificate.
You will also need to modify the /etc/iptables.save file to take into account the new IP 240.3.3.4

You must also modify the udhcp configuration to use a different DNS server than local. And you can also uninstall bind9 because it's no longer needed.

And you also need to update the web files, for that:

cd /root/
rm -rf tesla-carplay
rm -rf /var/www/carplay/*
git clone https://github.com/marcdubois71450/tesla-carplay.git
cd tesla-carplay
cp static/* /var/www/carplay/
npm i
reboot
