Extract and store impact assessment methods

Extract these methods

Put into a the LCIAformatter LCIAMethod format

@bl-young two questions in preparation for lciafmt ingestion:

1. Looking at the new LCIA methods file, do we need to map the elementary flows to FEDEFL to get the needed Context values?
2. Are the "Item(s)" and/or "Jobs" units associated with the Jobs and Labor Hours economic flows appropriate? Or would FEDEFL mapping resolve this too? I ask because the LCIAMethod mentions the flow unit field "uses olca-ipc.py units", within which I don't see "Jobs".

@a-w-beck Lciafmt handles both those things.

Also @WesIngwersen I've excluded the "WARM (MTCE)" method and factors from the methods file because they are defined on the "GHGs" impact category, which has indicator units of MTCO2E (rather than MTCE).

The factor values look correct (i.e., scaled by 0.27 vs the true MTCO2E factors), but just wanted to offer a heads-up.

@a-w-beck I don't think there is a need to exclude the method.. I understand it doesn't provide a lot of additional info, but it is used in WARM

I've got the initial script in place to apply this in the lciafmt. I few things to note based on what came out of warm in f8b3a75.

• The reference unit and the name in openLCA for WARM (Labor hours) is wrong. It says Jobs but it should be Labor hours
• The units during flow mapping are proving somewhat tricky. LCIAfmt will defer to mapping when the source UUID matches so it basically ignores context and unit. However in openLCA the unit that gets exported for the indicators does not have to be the default unit. That is, the csv uses t and btu while the mapping file assumes SI units kg and MJ. This also a problem for the economic flows which get converted to 2012 dollars through the mapping file. Initially I would propose that in WARMer we do the conversion of t -> kg and btu -> MJ (and also MTCO2E -> kg) before exporting
• I would propose we overwrite the Method field and just replace it with WARM or WARMv15

made the fixes above with 6d5b8d6
and added back MTCE ab09693

I think this should be done, but should do a final review of the ultimate method in https://github.com/USEPA/HIO/blob/main/lciafmt/create_WARM_LCIA.py
