Fix undefined prefixes

[whikloj]

GitHub Issue: n/a Follow of on #44

This PR fixes the issue identified by @dannylamb in this comment

What does this Pull Request do?

Items with prefix mappings unknown to EasyRdf end up with default prefixes (ns0, ns1, ns2, etc)

This allows a user to add prefix/URI mappings to the recast service and have them appear.

What's new?

• Does this change require documentation to be updated? yes, included
• Does this change add any new dependencies? no
• Does this change require any other modifications to be made to the repository (ie. Regeneration activity, etc.)? no
• Could this change impact execution of existing code? no

How should this be tested?

Prior to this PR any resource transformed would get anonymous prefixes for things in the http://fedora.info/definitions/v4/repository# and http://pcdm.org/models# namespace URIs.

After this PR, they will appear as fedora: and pcdm: though this is configurable.

Spinning up a base box right now, but can test this soon @whikloj.

Thx for the documentation, too.

Taking my name off this one since I'm super busy for the next week or so. :(

Although, ansible-role-crayfish's template for Recast needs to be updated to include the common prefixes (see the new example config) before anyone will notice the improvement...
