Add zenodo json

[chahank]

This is a proposal to a .zenodo.json metadata file which would have to be adapted before each release. It allows to specificy the authors instead of using the github contributors to this repository. Since this is a repository to keep scripts for papers, it could be a natural option to make the authors of the added paper in each release also the authors on zenodo of the release.

Information:
https://developers.zenodo.org/#add-metadata-to-your-github-repository-release

Please also have look at the metadata file for the latest release:

Suggestion by @peanutfun : shall we make a general author CLIMADA project?
