Improvement: Extend logging interface

[Retro64]

Authmosphere was initially designed to fit arbitrary logger-interfaces matching the interface of log4js.

Extend the logging-interface to support other logging interfaces like the interface of pino.

[Retro64]

It looks like the types are also not compatible with the native log4js types - which would be compatible to the pino types, changing
from

type LogFunction = (message: string, error?: any) => void;

to

type LogFunction = (message: string, ...args: any[]) => void;

should fix the problem and should also be fully downwards compatible and not breaking.
