Update number.py to increase comfort setting to 11kW

Since Alfen firmware 6.4.0 phase switching during solar charging functions properly. Therfore increase in comfort setting level makes sense. This limit can be used to switch phases.
People that use the charger on a 32A fuse as 22kW charger can manually increase this limit. I think most chargers and car combinations will be capped at 16A and 11kW.
