a CallbackLogger does not pass enough information to callback function

Problem

When using a custom logger (a CallbackLogger), the callback is called with [message:string, level: LogLevel] and that's it. CallbackLogger does not override addContext; its prototype contains Logger.addContext() which throws away the extra information. This extra information is most certainly useful to someone using a custom logging function.

Suggested Solution

CallbackLogger.log() should look like this (changes highlighted):

/**
 * Print a log message.
 *
 * @param message  The message itself.
 * @param level  The urgency of the log message.
 */
override log(message: string, level: LogLevel, ...args: [ts.Node?] | [number, MinimalSourceFile]) { // 👈
    super.log(message, level);
    this.callback(message, level, ...args); // 👈
}
