Reorganize & update script

[rgnldo]

1. The script must find the WAN interface and the router's IP CIDR insert in the file suricata.yaml
2. Only requirement: disable AiProtection. Remove the HND and QOS router requirement. Other users have tested it on other non-HND and QOS routers successfully.
3. Remove Skynet disable/remove requirement
4. There are situations where AiProtection is disabled in the GUI, not in NVRAM, preventing installation.

• To resolve this:

nvram set TM_EULA=0
nvram commit
service start_reboot
