Calculates a CoC level FMR by taking a weighted average of the county FMRs in the CoC. The weights are the share of the CoC population from each county.

process_split_county_fmr: Convert sub-county FMRs to county FMRs
Calculates a weighted average FMR for the counties that are in more than one FMR region. County subdivisions are unique to an FMR area so we take the weighted average of FMRs in the county subdivisions to get the county level FMR.
