L1233/L2233 water chunks could be simplified

I should have made a comment/issue on all of these files in the Level 1 version of this chuck (L1233), but this Level 2 chuck and the preceding one utilize repetitive data in all the input files. The input data files should be condensed as it is repeating the same information for all the years and all of the technologies. This makes the R code longer and more complicated than it should be. We'll have to address this later.

For the next round, I think we can redesign this whole process to be simpler.

@skim301 I'm checking on old issues to try to clean up the gcamdata repository - it looks like this issue has not been taken care of yet, correct?

I also want to make sure I understand the issue. I think you may have been referring to a few different things:

1. There are a bunch (20+) of energy/A23 files. Some of these could potentially be combined
2. module_energy_L223.electricity, module_gcamusa_L223.electricity_USA, and module_water_L2233.electricity_water all produce a ton of outputs (40-60 each), which ultimately just get combined into a few xmls.

Are both of these what you wanted to address?

@russellhz It's been so long I'm not sure what exactly I was referring to other than that we could condense some repetitive input data. I'm not sure if it matters at this point, but making an effort to reduce repetition and excessive output is a good idea. What ever you think is a good way to clean this up and minimize the ton of outputs is fine with me.
