WiFi Logger for esp32

[VeWare]

ESP32 WiFi logger - Log messages over WiFi, using either TCP, UDP or Websockets

• Generates log messages with same format as ESP-IDF Logging API.

• Can route logs generated by ESP_LOGX(), provides a custom function to log messages over wifi.

• Follows ESP-IDF log color pattern for different log levels.

• Using UDP as network protocol provides lowest latency.

• Minimal test condition - minimum free heap = 220388 bytes.

• TCP performance is mid-way:

• Minimal test condition - minimum free heap = 216537 bytes.

• Using Websockets provides the worst latency:

• Minimal test condition - minimum free heap = 205416 bytes.
