Add publication information

[rettinghaus]

It's kinda hard to cite the songs, because there are no officially released versions and no information on publication date/place is available.

Things to consider:

• add a CITATION.cff to the repo
• make official releases through GitHub
• add some words to the README about publication date (and if possible place)
• connect the repo to Zenodo and receive a DOI for every release

Thanks your input @rettinghaus. I'm open to any such changes.

Currently, the README has the following recommended citation:

@inproceedings{GothamJonas2022,
 abstract = {The OpenScore Lieder Corpus is a collection of over 1,200 nineteenth century songs encoded by a dedicated team of mostly volunteers over several years. Having reported on the initial phase, motivations, design, and community-oriented aspects of the project before, we present here the first, stable, large-scale release of this corpus specifically designed for MIR researchers, complete with comprehensive, structured, linked metadata. The corpus continues to be available under the open CC0 licence and represents a compelling dataset for a range of MIR tasks, not least given its unusual balance of large-scale with high-quality encoding, and of diversity (songs by over 100 composers, from many countries, and in a range of languages) with unity (centred on the nineteenth-century lieder tradition).},
 author = {Gotham, Mark Robert Haigh and Jonas, Peter},
 title = {{The OpenScore Lieder Corpus}},
 keywords = {mec-proceedings, mec-proceedings-2021},
 pages = {131--136},
 publisher = {{Humanities Commons}},
 isbn = {978-84-1302-173-7},
 editor = {M{\"u}nnich, Stefan and Rizo, David},
 booktitle = {{Music Encoding Conference Proceedings 2021}},
 year = {2022},
 doi = {10.17613/1my2-dm23},
 bibbase_note = {<span style="color: green; font-weight: bold">Best Poster Award.</span>},
 displayby = {Contributions from MEC 2021}
}

To clarify then, would you like to see this altered or added to? Or simply a .CFF version of the same? Or are keen to cite the repo without citing MEC?

Thank again for the input.

[rettinghaus]

Yeah, it would be good to have a possibility to cite the repos directly without needing to point to an article on the matter. Since the presentation during MEC several commits have been made, so it is ever uncertain in which state the corpus actually is. Integration with Zenodo would help here, because then there'll be always at least a definite version and DOI one could point to.
