dopplerchase/DRpy: First major release

Since starting this package, I have learned a lot about open-source software development. Given DRpy's recent visibility (thanks twitter), I am starting to get requests of 'how do I cite DRpy?'. To facilitate this, I am releasing version 1 today. There has been no major changes to the recent versions of the code, but now the github repo will get assigned a doi on zenodo, which will allow people to cite the code and re-produce paper results by archiving versions of the code.

Thanks everyone for their interest.
