Run fmda from wrfouts #63
Description
Martin had fmda from wrfout in https://github.com/vejmelkam/fmda. A version is in wrfxpy in https://github.com/openwfm/wrfxpy/blob/master/src/fmda/fuel_moisture_da. I made some fixes and played with it around 9be3fe1 in summer 2018 but it would not run from the wrfout on the finest (fire) domain because there was not enough RAWs there, usually none.
We should run fmda from wrfout in one of the outer domains and dowscale to the domain(s) where the fire model runs.
