CoreS3 Conflict with USB / USBHidKeyboard Libraries

[richstokes]

Describe the bug

Trying to have the M5Stack CoreS3 act as a USB keyboard, while using other M5 features, such as the LCD display, results in a conflict when compiling.

To reproduce

This works fine, and will have the M5CoreS3 act as a USB keyboard, sending the 'c' key every 4 seconds:

#include "USB.h"
#include "USBHIDKeyboard.h"
USBHIDKeyboard Keyboard;

void setup() {
  // Remember to set USB mode (not upload mode) to USB-OTG under tools menu
  Keyboard.begin();
  USB.begin();
}

void loop() {
  Keyboard.print("c");
  delay(4000);
}

However attempting to use the M5CoreS3 library at the same time results in compilation errors, e.g:

#include "USB.h"
#include "USBHIDKeyboard.h"
#include <M5CoreS3.h>
USBHIDKeyboard Keyboard;

void setup() {
  // Remember to set USB mode (not upload mode) to USB-OTG under tools menu
  Keyboard.begin();
  USB.begin();
  M5.begin(); // Init M5CoreS3
  M5.Lcd.fillScreen(GREEN);
  delay(500);
}

void loop() {
  Keyboard.print("c");
  delay(4000);
}

Expected behavior

We should be able to have the device act as a USB HID/Keyboard, while being able to use other features of the stack. My goal is to have a device that receives data via wifi and then sends keyboard commands via USB.
