Combine archive and archive-location fields to match publisher field

[mkdjr]

Issue

Currently, the information about the name and location of an entry's publication and/or archive can be stored in Hayagriva. However, the archive and publisher fields do not store data in the same way.

Publisher

Information regarding an entry's publisher can be stored either as a name:

publisher: <string>

or as an object with separate keys for its name and location:

publisher:
    name: <string>
    location <string>

Archive

Yet archival information is stored in a flat structure:

archive: <string>
archive-location: <string>

Proposal

Align archival information formatting with that of the publisher field, such that it can be stored as:

archive: <string>

or

archive:
    name: <string>
    location: <string>

and deprecate the archive-location field.
