committing to dave's branch
* new LORIS Zenodo DOI (10.5281/zenodo.5177111) Created by Samir today - it points to all releases of LORIS. 
* Adding my name 

FYI @driusan in case you see this commit message - all authors of the repo are automatically linked from the zenodo entry, it might make more sense to point to that list if possible.
