New geek handheld console

Overview

This is an upgraded version of the geek handheld console I made before. Compared with the previous version, this version mainly made the following changes:

The main control has been changed from STM32F030CCT6 to GD32F303CCT6. The main frequency is higher and can reach 200M. The peripherals are more powerful.
A new microphone is added to the built-in DAC output. It can be combined with an SD card to realize the recording function.
A new LORA module can be combined with the microphone to realize the wireless intercom function.
The newly added vibration motor can bring better operational feedback.
A DAC output interface, an ADC interface, a serial port, an SPI interface, and three ordinary IOs are reserved in the form of pads.

If there are no major problems with this version of the hardware, we will slowly tinker with this version of the hardware in the future, and we may do some expansion projects based on this handheld console.
