Add the Zenodo concept DOI to the citation metadata.

[roytsmart]

This is the follow-up to #10. Zenodo archived v0.2.1 and created the DOIs:

• concept DOI (always the latest version): 10.5281/zenodo.23107787
• v0.2.1: 10.5281/zenodo.23107788

The Zenodo record picked up the CITATION.cff metadata: the author with his ORCID, the license, the keywords, and the abstract as its description. The concept DOI never changes, so this is the last citation change the repo needs.

Changes

• CITATION.cff: the concept DOI goes under identifiers, as in Add the Zenodo concept DOI to the citation metadata. interface-region-imaging-spectrograph#56. I didn't use the top-level doi field, so Zenodo can't mistake it for the DOI of a new release.
• README: a Zenodo DOI badge in the header.
• README and docs: the Citation section explains the difference between the concept DOI and the version DOIs, and the BibTeX example now includes the doi field.

Testing

• cffconvert --validate reports: "Citation metadata are valid according to schema version 1.2.0."
• Both DOIs resolve on doi.org.
