year_one cost calculations in REopt.jl

[adfarth]

Notes on "year_one" cost outputs:

These are currently actually year_zero costs, since they use user cost inputs, which are assumed to be year 0. To change these to "year_one" costs, we need to apply an escalator. We should report these costs in year_one dollars, and therefore should not discount these back to year 0. Extra complication: these costs use "annualized"/avg annual production values (e.g. PV production) and therefore are not actually true costs for any given year. But as close as we can get without re-solving REopt for individual years' production values!

@Bill-Becker this is not complete; my understanding is that we pushed this back to FY24.
