- Upgraded representation of dust processes (Klose et al., GMDD 2021)
    - Aerosol-radiation interaction allowed (only dust mode fully tested)
    - Implementation of secondary inorganic nitrate/ammonium aerosols and hydrolisis of N2O5.
    - Previous developments described in Perez et al. (2011), Spada (2015), Badia et al. (2017) and Di Tomaso et al. (2017). 
    - Preliminary version of the interface allowing flexible chemistry with the CAMP library (not fully tested)
    - NetCDF output
    - New diagnostics interface
    - Compatible with IFS and global CAMS pressure level boundary conditions
    - Configuration modes fully tested in this release: DUST, DUST_DA
    - Configuration modes with partial developments not fully tested in this release: GLOBAL_AEROSOLS, REGIONAL_CHEM, NESTING
