A script to run on a single line for OpenWrt

[itdoginfo]

Merged three of your scripts into one. This has the following advantages:

• Run with one command. No git and no need to run the three scripts one by one
• Installing the necessary packages for OpenWrt
• Displayed router information

I also fixed the kill for iperf3. I often had it failing on a PID file. Kill by port works without issues. Also added a delay. Command for download and run (my fork for example):

sh <(wget -O - https://raw.githubusercontent.com/itdoginfo/wg-bench/master/openwrt-benchmark.sh)

Output

Packages:
Wireguard already installed
Iperf3 already installed
ip-full already installed
kmod-veth already installed
psmisc already installed
