Update parent logger level does not cascade/propogate to children

[ogallagher]

If I create a parent logger

const logger = pino({name: 'parent', level: 'debug'})

and a child logger,

const child = logger.child({name: 'child'})

the child logger will inherit the log level from the parent. But if I later update the parent logger's level,

logger.level = 'error'

this does not change child.level. Is this intended behavior? Perhaps there could be an option to cascade level changes towards a logger's descendants?
