update tutorials using eodag-cube

[sbrunato]

Update the following tutorials, using eodag-cube:

• https://eodag.readthedocs.io/en/latest/notebooks/tutos/tuto_cds.html
• https://eodag.readthedocs.io/en/latest/notebooks/tutos/tuto_ecmwf.html
• https://eodag.readthedocs.io/en/latest/notebooks/tutos/tuto_meteoblue.html

Also use cartopy , like on this example that plots Sea ice area fraction from an dedt_lumi product type on an European cropped area:

import cartopy.crs as crs
import cartopy.feature as cfeature

# europe crop
mask_lon = (ds.longitude >= 348) | (ds.longitude <= 48)
mask_lat = (ds.latitude >= 32) & (ds.latitude <= 72)
ds_eu = ds.where(mask_lon & mask_lat, drop=True)

fig = plt.figure(figsize=(8,6))

ax = fig.add_subplot(1,1,1, projection=crs.Mercator())

ax.add_feature(cfeature.COASTLINE)
ax.gridlines(draw_labels=True)

sc = plt.scatter(
    x=ds_eu.longitude[::5], y=ds_eu.latitude.data[::5], c=ds_eu.siconc[::5], 
    cmap="cool", s=1, transform=crs.PlateCarree()
)
plt.colorbar(sc, label=ds.siconc.long_name)

plt.show()

@sbrunato I started looking at the cds tutorial and one potential issue I can see with replacing the call to .download by a call to eodag-cube's .get_data is that it requires a band argument which in the case of grib data is not known until we download the data and look at the file names.

Unless there's a way to know it in advance and I'm not aware of it?

As per discussion with @sbrunato, let's use a regular expression similar to .*\.grib$ to match the single grib file that will have been downloaded.
