Disruptive changes: - tag types are 2-byte long with new values - GET_SLOT_INFO returns 32 bytes as tag types are now 2-byte long - "enable" is not common to one slot anymore but bound to the HF or LF part - GET_ENABLED_SLOTS returns 16 bytes as we get "enabled_hf" and "enabled_lf" for each slot - SET_SLOT_ENABLE needs 3 bytes slot_number|sense_type|enable as we need to specify to enable HF or LF - slotConfig changed a lot but this is internal to the fw and its flash and a function does the format conversion on first boot after flash so slot data is preserved on fw upgrade, but if one downgrades to a previous version, data will be erased.
