feat: add default value for LogOptions to createLogger

[Blaubeeree]

Description

Add an option to define a default value for LogOptions when creating a Logger. This can be used e.g. to create a Logger that per default prints out a timestamp without having to specify every time:

let logger = createLogger("info", {defaultLogOptions: {timestamp: true}})
logger.info("Hello World!")
// 5:47:54 PM [vite] Hello World!
