Features

Add ARCOERA5 interface for accessing ARCO ERA5 model level data. This interface requires the metview python package.
Add ARCO ERA5 tutorial notebook highlighting the new interface.

Breaking changes

Reduce CocipParams.met_level_buffer from (200, 200) to (40, 40). This change is motivated by the observation that the previous buffer was unnecessarily large and caused additional memory overhead. The new buffer is more in line with the typical vertical advection path of a contrail.

Fixes

Raise ValueError when list[Flight] source is provided to Cocip and the copy_source parameter is set to False. Previously the source was copied in this case regardless of the copy_source parameter.
Fix broken link in the model level notebook.

Internals

The datalib.parse_pressure_levels now sorts the pressure levels in ascending order and raises a ValueError if the input pressure levels are duplicated or have mixed signs.
Add new MetDataSource.is_single_level property.
Add ecmwf.Divergence (a subclass of MetVariable) for accessing ERA5 divergence data.
Update the specific humidity interpolation notebook to use the new ARCOERA5 interface.

Tests

[x] QC test passes locally (make test)
[x] CI tests pass
