Custom OpenWrt complier for GL-MT1300

This repo using github actions to complile firmware for my GL.iNet Beryl(GL-MT1300) , which is minimum-obtrusive to the latest stable version of OpenWrt but only optimize for console game accelerator use. It's a reasonable product positioning for a low-end(mt7621) router.
With that said it's fine to use it complile for other routers in support list.

• Integrated with wlan offload optimization and fullcone-NAT support to improve connection quality
• Multiple WAN function allows you to increase the net speed exponentially
• Build your own global transit between the router and private server. Xray is recommended due to its low CPU cost and UDP support as claimed
• Fully support LTE modules on USB port
• Using nginx to provide luci and other web page over https. Remote access also available
• HomeAssistant intergration compatible
