New Materials Cloud Archive file urls

[eimrek]

The Materials Cloud Archive (https://archive.materialscloud.org/) will soon migrate to a new version and as a results, the direct file download urls will change.

I found two places where these urls are used:

aiida-pseudo/src/aiida_pseudo/cli/install.py

Line 114 in 92e1c24

url_template = 'https://archive.materialscloud.org/record/file?filename={filename}&parent_id=19'

and

aiida-pseudo/tests/cli/test_install.py

Line 202 in 92e1c24

filepath_archive = 'https://archive.materialscloud.org/record/file?filename=fake-url'

In order to anticipate the URL change and make sure this doesn't break, we should probably already start supporting also the new url.

@vgranata Do you already know what the new url will look like?
