DA14531 BLE HID 中的 Feature report 的傳送與接收，該應用哪個函數來實現

网址中找到 DA14531 BLE  HID 的范例

https://github.com/dialog-semiconductor/BLE_SDK6_examples/tree/main/interfaces/HID-Gamepad-Digitizer

为实现蓝芽触控板(Device)应用，将范例程式改成下方图式

从范例能得知INPUT REPORT 资料，只须呼叫 app_hogpd_send_report ()function 就能将资料回丢给 Host，
然而 Feature report 的 read write 分别该应用哪个函数及操作流程来实现， Device Feature report 才能与 HOST read write 资料.

HID_TOUCHPAD_MAX_COUNT_REPORT_ID   0x02

HID_TOUCHPAD_INPUT_REPORT_ID               0x03
