The GBIF (https://www.gbif.org/) deposits most records under the titles:
* 599243 GBIF Occurrence Download
* 41176 Occurrence Download
Mark them as "stub" for the moment

> include release_month as a top-level extra field [...] to
auto-populate the schema field from that

Datacite defines placeholders for unknown values:

> always include extra values for the respective DOI registrars
(datacite, crossref, jalc), even if they are empty ({}), to be used as a
flag so we know which DOI registrar supplied the metadata.
|
| |
|
|
|
|

As [...] we will soon add support for release_month field in the release schema.

> The convention for display_name and raw_name is to be how the name
would normally be printed, not in index form (surname comma given_name).
So we might need to un-encode names like "Tricart, Pierre".
Use an additional `index_form_to_display_name` function to convert index
from to display form, heuristically.

* add missing langdetect
* use entity_to_dict for json debug output
* factor out code for fields in function and add table driven tests
* update citeproc types
* add author as default role
* add raw_affiliation
* include relations from datacite
* remove url (covered by doi already)
Using yapf for python formatting.

Current version succeeded to import a random sample of 100000 records
(0.5%) from datacite.
The --debug (write JSON to stdout) and --insert-log-file (log batch
before committing to db) flags are temporary added to help debugging.
Add few unit tests.
Some edge cases:
a) Existing keys without value requires a slightly awkward:
```
titles = attributes.get('titles', []) or []
```
b) There can be 0, 1, or more (first one wins) titles.
c) Date handling is probably not ideal. Datacite has a potentiall fine
grained list of dates.
The test case (tests/files/datacite_sample.jsonl) refers to
https://ssl.fao.org/glis/doi/10.18730/8DYM9, which has date (main
descriptor) 1986. The datacite record contains: 2017 (publicationYear,
probably the year of record creation with reference system), 1978-06-03
(collected, e.g. experimental sample), 1986 ("Accepted"). The online
version of the resource knows even one more date (2019-06-05 10:14:43 by
WIEWS update).

Currently using two external libraries:
* dateparser
* langcodes
Note: This commit includes lots of wip docs and field stat in comment,
which should be removed.
