Incompatible results between version 0.6 and earlier

[PierreGtch]

The results computed with MOABB version 5.0 and earlier will be incompatible with version 6.0 and later because we changed many dataset names and codes (#448 #455) and the sessions and runs naming scheme (#471 ).

How should we warn the users about that?

It looks like an API break for me. It may be time to make the 1.0.0 version or find a way to load the results. What do you think @sylvchev?

[sylvchev]

Not an API break for me, as this concern the results of computation and not the code. Nonetheless, I agree that we should move to 1.0.0 version! This is time and we should allow users that want to keep their previous results to stick with 0.x versions

Next question is, since we will move to a new major version that allow API breaks, do we have some API to break? It will a good opportunity, next one could be in a long time! I'm thinking about changes in names or parameter names of functions (to keep homogeneity with other libraries). Maybe a good time to see if we have a better take on evaluation.process and evaluation.evaluate for example.
