Feature log filter

[CMCDragonkai]

Description

This adds the ability to filter logs based on key path using a regex.

const logger = new Logger('root');
const interLogger = logger.getChild('inter');
const leaf1Logger = interLogger.getChild('leaf1');
const leaf2Logger = interLogger.getChild('leaf2');
logger.setFilter(/^root\.inter/);
leaf1Logger.info('INFO MESSAGE');
leaf2Logger.info('INFO MESSAGE');
logger.setFilter(/^root\.inter\.leaf1/);
leaf1Logger.info('INFO MESSAGE');
leaf2Logger.info('INFO MESSAGE');
logger.setFilter(/^root\.inter\.leaf2/);
leaf1Logger.info('INFO MESSAGE');
leaf2Logger.info('INFO MESSAGE');

This is a simple quick feature, but it doesn't cover the total range of log filtering worth doing. Any complex log filtering should be done on the frontend not on the origin of logs. Discrete data should be captured and filtered down the line.
