Add option to pass custom logger to rrweb record

[wbobeirne]

I use a custom logger in my frontend to send logs server side for analysis. Unfortunately I'm unable to record any rrweb debug logging since it uses a console.log with no way to override it:

rrweb/packages/rrweb/src/replay/index.ts

Lines 1892 to 1899 in f756790

	private debug(...args: Parameters<typeof console.log>) {
	if (!this.config.showDebug) {
	return;
	}
	// tslint:disable-next-line: no-console
	console.log(REPLAY_CONSOLE_PREFIX, ...args);
	}
	}

It'd be nice if there was an option for passing a custom function that would be called instead. Ideally the call happens before the showDebug check so that we can implement custom logic for showDebug instead of having to call setConfig to update it.

Maybe I can expand the showDebug option to receive a custom logger just like what we did in the console plugin. But I have one thing not sure about. Do I have to replace the warn log like this: https://github.com/rrweb-io/rrweb/blob/master/packages/rrweb/src/replay/index.ts#L1962-L1967 with the custom logger?

Do I have to replace the warn log... with the custom logger?

For my use case, that would be ideal. I'm trying to send rrweb logs to my server so that we can debug issues in production, so I'd like any and all logs to be accessible.
