pw_console: Json Log file formatter

New JsonLogFormatter handler to save pw_console device logs with
metadata fields to json. For example running:

$ pw-system-console --verbose -d /dev/ttyACM0 -b 115200 \
  --json-logfile logs.json \
  --proto-globs pw_rpc/echo.proto \
  --token-databases \
out/stm32f429i_disc1_stm32cube.size_optimized/obj/pw_system/bin/system_example.elf

$ tail -F logs.json | jq

{
  "message": "System init",
  "levelno": 20,
  "levelname": "INF",
  "args": [
    "0:00",
    "pw_system ",
    "System init"
  ],
  "fields": {
    "module": "pw_system",
    "file": "pw_system/init.cc",
    "timestamp": "0:00"
  }
}

{
  "message": "Pigweed is fun 10x!",
  "levelno": 20,
  "levelname": "INF",
  "args": [
    "0:00:00.003",
    "user_init ",
    "Pigweed is fun 9x!"
  ],
  "fields": {
    "module": "user_init",
    "file": "pw_system/example_user_app_init.cc",
    "timestamp": "0:00:00.003"
  }
}

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.

For more information please see our website: https://pigweed.dev/.
