Allow importing a DataFrame as a ColocatedData object

[thorbjoernl]

Is your feature request related to a problem? Please describe.
Allow creating a ColocatedData object from a pandas DataFrame. Basically the inverse of ColocatedData.to_dataframe().

Would allow for another path for injecting ColocatedData into Pyaerocom.

Is it possible to also allow for xarray dataset to be injected as ColocatedData? Let's say I do the collocation manually using the pyaerocom api i.e.

coldata = pya.colocation.colocator.colocate_gridded_ungridded(rsdscs,data,ts_type='monthly',harmonise_units=False)
ds = coldata.data
ds.to_netcdf("awsome_colocated_data.nc")

which returns coldata as a Xarray dataset that i can save to disk. Could i inject this into pyaeroval for visualization? In let's say by reading it in my config.py?

@Ovewh In theory if you do it correctly it is possible. But this interface for picking up collocated data objects in a WIP https://pyaerocom.readthedocs.io/en/latest/pyaerocom-tutorials/making_a_colocated_data_object_with_pyaerocom.html
