OCPP 2.0.1 support

OCPP 2.0.1 support is added to Firmware release 2.1.0, with profiles Core, Advanced Security and Local Authorization List. This implementation is certified by the Open Charge  Alliance with certification number OCA.0201.0014.CS. All certified use cases are listed in Chapter 7.
More use cases are supported because of ISO15118 improvements and smart charging necessities.
