This is a nice little chip info tool that I've created some time ago.
When building with `-D WLED_DEBUG`, it reports some interesting information about your ESP32 on serial monitor.

it's possible that volume samples become negative. In this scenario, our simple noise gate does stupid things, and it looks like "effects temporarily lost the sound".
This fix improves the situation, and makes sure that volume samples are always >= 0.
This fixes a "division by zero" in WLED_DEBUG code.
LittleFS init seems to take some time, so we can arrive at "Loops/sec" with 0 loops executed --> crash.
- Add XandY struct
- Add ArrayAndSize struct
- to be used in jVectorMap (instead of jMapDoc) :Smaller footprint!!
- introduce docChunk to parse with ArduinoJson in chuncks (smaller size!)
- platformio: add USERMOD_MPU6050_IMU and ElectronicCats/MPU6050 @ 0.6.0 to esp32mdevums
- USERMOD_MPU6050_IMU: update readme.md and usermod_mpu650_imu.h
- usermod_v2_games: support for USERMOD_MPU6050_IMU, add mode_IMUTest and class Frame3D and mode_3DIMUCube, remove old gyro handling
- usermods_list.cpp: add USERMOD_MPU6050_IMU
