Add datasource method should ensure it's well added

[tristanlatr]

Describe
Like in the code snippet, the add() method should call dsAddDataSourcesStatus , make sure there is no error or raise an Exception if the Datasource were not added.

Only if special argument check_added=True to keep compatibility.

** msiempy versions:**

• msiempy: 0.3.3
