Shift fake tank pressures up by 30bar

Browse source 
This is a rather arbitrary value, intended to create actually valid
pressure values for Uwatec Memomouse users - since we treat 0bar as
invalid pressure value, this simply creates an arbitrary '30bar + delta'
to '30bar' consumption graph (since all the Memomouse devices give us is
the pressure delta that was used during the dive).
