LOGLEVEL_WBXML does not work with ZLog::SpecialLogUser()

EGroupware currently updating from z-push 2.3.x to lastet 2.5.0 installed via composer (https://packagist.org/packages/egroupware/z-push-dev from our own GitHub fork of z-push. I'm more then happy to use an official z-push composer package, if there were one.)

We call ZLog::SpecialLogUser() to get a log for a specific device and have LOGUSERLEVEL = LOGLEVEL_DEVICEID, to log the XML.

This no longer works, as WBXML-decoder and -encoder call ZLog::IsWbxmlDebugEnabled(), which does not take the ZLog::SpecialLogUser() into account.

Either ZLog::SpecialLogUser() must track and report it in ZLog::IsWbxmlDebugEnabled(), or the logger-backend eg.
public function HasSpecialLogUsers()

{     return !empty($this->specialLogUsers) || $this->isAuthUserInSpecialLogUsers; }

Or we need an other way to enable a device-specific log.

I'm happy to implement or fix it, thought I want to ask first how you want to have it done
