Describe the bug

• Pyaerocom version: up to 0.21.0.dev0

The variable concso4coarse is only defined in ebas and in use for the emep-model.
In ebas, it reads from the pm10 or aerosol matrix without subtracting pm25, so it is not coarse.
The emep model does not know about sulphate larger than pm25, neither coarse nor pm10 exists.
The glob_defaults.py rename the concso4coarse to SO4_PM10.

The same is true for concnh4coarse and concsscoarse.
In the same commit, also the name fine was introduced for concnh4fine and concso4fine which isn't used elsewhere. fine should be named consistently pm25

Expected behavior
concso4coarse is named concso4pm10 everywhere in pyaerocom
coarse is named pm10 in all pyaerocom-names
fine is named pm25 in all pyaerocom-names
concso4coarse/concso4pm10 is no longer used in comparison with the emep-model.
