t113_86 box modified version

Thanks to the developer Fan Hua for open-sourcing the T113 86 box and providing detailed SDK installation instructions and
 
demonstration videos.
The Allwinner T113-S3_86 box application is here, completely outperforming the previous ESP32S3 version!
 
This modified version includes the following changes:
 
The removed Bluetooth serial port has been reconnected; one A port has been changed to a C port for ADB use (A to A cables are hard to find); the SPI FLASH has been moved; the wiring has been adjusted; the RST button has been moved and a flashing button has been added; the audio wiring has been adjusted, adding an analog ground and separating it from the digital ground; two test buttons have been added; the RY3730 screen backlight chip is hard to find, so it has been replaced with a SY7200; an analog microphone has been added for audio spectrum pickup.
 
Note that the microphone is soldered horizontally; the microphone is a high-sensitivity 4015P direct-plug back electrode type 36±1DB anti-interference electret microphone - Taobao (taobao.com). For
