Add new Springshare sources Libguides and Research Databases

[ghukill]

What does this PR do?

This PR adds two new sources that transmogrifier can handle: libguides and researchdatabases.

The overall approach is this:

• a generic OAI Dublin Core transformer OaiDc
• a Springshare OAI transformer SpringshareOaiDc that extends OaiDc
• both new sources use SpringshareOaiDc transformer as defined in the source configurations

This PR also updates dependencies.

How can a reviewer manually see the effects of these changes?

Example of libguides transformation:

pipenv run transform -s libguides -i "tests/fixtures/oai_dc/springshare/libguides/libguides_record_all_fields.xml" -o "output/libguides.json"
