settings: interpret temp basal type

I **was** missing a few bytes before; they indicate which type of temp basal
rate is enabled.  Another extra byte indicates whether or not the pump has
enabled the paradigm meter link.

{'low_reservoir_warn_point': 20, 'keypad_lock_status': 0, 'maxBasal': 2, 'temp_basal': {'percent': 100, 'type': 'Units/hour'}, 'paradigm_enabled': 0, 'insulinConcentration': 100, 'audio_bolus_enable': True, 'variable_bolus_enable': False, 'alarm': {'volume': 3, 'mode': 2}, 'rf_enable': True, 'block_enable': False, 'timeformat': 0, 'auto_off_duration_hrs': 0, 'audio_bolus_size': 2.0, 'selected_pattern': 0, 'patterns_enabled': True, 'insulin_action_type': 5, 'maxBolus': 10.0, 'low_reservoir_warn_type': 0}
