review use of license, termsOfUse, termsOfAccess

[pdurbin]

While working on #30 I'm noticing some strangeness with termsOfUse and termsOfAccess. To keep the other issue as a "trivial" I'm opening this new issue for a deeper look.

There seem to be several cases.

CC0 license, termsOfUse dropped

For these we should probably drop termsOfUse from the JSON because it seems to be dropped by Dataverse anyway.

No license but termsOfUse describes CC0

For these we should probably just add a CC0 license and remove termsOfUse because termsOfUse is describing CC0 anyway. Otherwise it doesn't make much sense.

termsOfAccess but no restricted files

These datasets specify termsOfAccess but because there are no restricted files, you can't easily see that it's set unless you are logged in as an author and edit terms. It probably makes sense to restrict a file or two for each dataset.
