Full Changelog: 1.3.1...1.4

Following issue #150 we changed the way we load cordex validation vocabularies from directly form ESGF to son file, as for CMIP.
other vocabularies were also updated.

Main change is the addition of a "cortex" sub-command to query CORDEX data distributed via the ESGF. Cordex views were added to the database.
Other minor changes are:

• made the request workflow clearer
• added a "saving file.." message were appropriate
• updated the CMIP6 CV vocabularies as of the 2021/04/29
• documentation and demo were also updated to reflect the new sub-command

Only change is fixing bug #143 , so it doesn't regenerate an error when querying CMIP5

Fixed issue #141
