Hotfix/_camx_mm consistent with _wrfchem_mm

[blychs]

This makes the camx_mm reader consistent with wrfchem_mm by incorporating "dz_m" instad of "layer_height_agl"
We had talked at the time of adapting it once the new wrfchem_mm reader was accepted.

@blychs I'm a bit confused.

Does your layer_height_agl correspond to alt_agl_m_mid in the WRF-Chem reader?
dz_m is the thickness of each layer, not height above ground level.

monetio/monetio/models/_wrfchem_mm.py

Lines 213 to 215 in 8c7af1c

	"height": "alt_msl_m_mid",
	"height_agl": "alt_agl_m_mid",
	"dz": "dz_m",

No, it doesn't. alg_agl_m_mid is the exact same thing here as in _wrfchem_mm. layer_height_agl was the layer height at the interface, which I was using later to create the thickness to calculate partial columns.
SInce the wrfchem reader went a different way, by calculating layer thickness in the reader, I am changing it to do the same, so that future code will work for both.
The TEMPO tool can already deal with the way that wrfchem does it.

[blychs]

That way, the TROPOMI tool (or any other) should work for both regardless, since the version loaded by MONETIO will look the same.

The NCDC website still having an issue, causing the test failures.
