/**
 * Huddly Logger class.
 *
 * Use HUDDLY_LOG_LEVEL env variable to configure the log level on the SDK. The following values apply
 * - DEBUG - log all gRPC messages
 * - INFO - log INFO and ERROR message
 * - ERROR - log only errors (default)
 * - NONE - won't log any
 *
 * Use HUDDLY_LOG_CHANNEL env variable to configure where the logs will be directed to. The following
 * values apply:
 * - CONSOLE - Write logs to system console
 * - FILE - Write logs to a dedicated file provided by HUDDLY_LOG_FILE
 *
 * USE HUDDLY_LOG_FILE env variable to specify the file where the logs will be directed to.
 *
 * @example
 * // Print all logs and redirect them to a file
 * export HUDDLY_LOG_LEVEL=DEBUG && HUDDLY_LOG_CHANNEL=FILE && HUDDLY_LOG_FILE=/users/johndoe/huddlysdk.log
 * node sdkexample.js
 *
 * // Print INFO && ERROR logs and redirect them to console out
 * export HUDDLY_LOG_LEVEL=INFO
 * node sdkexample.js
 *
 * // Disable all log output
 * export HUDDLY_LOG_LEVEL=NONE
 * node sdkexample.js
