Dataset problem: EC-Earth3-Veg, EC-Earth3

[mwjury]

When doing an ensemble_statistics, metadata has to be the same between the single ensemble members. Depending on #673 for the error to appear. Currently tested for CMIP6 Amon TAS runs having data for this 5 experiments: historical, ssp126, ssp245, ssp370, ssp585.

This leads to problems with (luckily on 2 so far):

• [x] EC-Earth3-Veg: #836
• [x] EC-Earth3: #837

In the case of EC-Earth3-Veg and TAS there are differences in latitude points and bounds of -9.9475983e-14. So some simple rounding should do the trick.

iris.exceptions.MergeError: failed to merge into a single cube.
  Coordinates in cube.dim_coords differ: latitude.

@valeriupredoi ensemble_statistics is opening new avenues for metadata discrepancies.

Same thing happening with EC-Earth3.
