eccodes dependency update (#947)

* eccodes changed variable names: i.p., gust -> i10fg

* requirements: apparently the need for fiona has ended with eccodes>=2.28

* pin geopandas down to 0.x for the time being

* dependencies: as long as geopandas is <1, fiona is automatically installed

* black the branch

* storm_europe: accept gust and alternatively i10fg

* find the appropriate data variable name

* dependencies: add/remove comments

* dependencies: pinning cfgrib is apparently not required anymore
