    Fix bug in storage fixed cost calculations
    
    In versions 2.0.0b3-2.0.5, fixed costs from all possible build years
    were applied each period, instead of only using the build years that are
    still in service in the current period. This increased the apparent cost
    of storage by approximately (study length) / (storage life). This commit
    fixes that bug.
