Export coriolis, unscale diagnostics at finish, add! callbacks directly to model too

[milankl]

Changes arose from #400

@miniufo changes now in #main

I should update my version. Also thinking other variables such as $\cos\phi$ and $\sin\phi$. I need these too when calculating the absolute angular momentum. Is there any easy way to do this like the exported coriolis function?

They are all in the RingGrids module, which is also documented here https://speedyweather.github.io/SpeedyWeather.jl/dev/ringgrids/ in short, you do RingGrids.get_*(::AbstractGrid) with * one of the following

julia> grid = rand(OctahedralGaussianGrid,4);

julia> RingGrids.get_

get_colat               get_colatlons           get_lat
get_latd                get_latdlonds           get_latlons
get_lon                 get_lond                get_nlat
get_nlat_half           get_nlon                get_nlon_max
get_nlon_per_ring       get_nlons               get_npoints
get_quadrature_weights  get_resolution          get_solid_angles
get_truncation
julia> RingGrids.get_lat(grid)

with lat in radians, colat in radians, d means degree, s means for every grid point and not just on the zonal rings or meridians.
