DOC: Update contributors

[nkeim]

This updates the Contributors list to include people who have made the largest contributions to the scientific capabilities and/or package maintenance in the past few years. It also removes the specific attributions on the Introduction page, since tracking that manually is likely to get messier as time goes on.

@vivarose , @freemansw1 , @anntzer Please review your name and ORCID in .zenodo.json and optionally add funding info to the end of the Introduction page.

Great! Thank you!
Maybe you noticed I stayed up late last night reading Trackpy issues.

I am working toward a GUI for Trackpy. In particular, I am supervising a group of three senior CS majors who are earning credit to write the GUI code. (It's over here for now: https://github.com/bakir/particle_tracking_gui). Maybe someday it will be good enough to be part of the soft-matter official offerings.

So I've been thinking about Trackpy.

Thanks for including me here. The ORCID is correct. For funding information I would like something like "Antony Lee's work on the package took place, in part, during his post-doc in Laurent Cognet's group at the Université de Bordeaux. This work was supported by a post-doctoral fellowship from the Fondation ARC pour la Recherche sur le Cancer." Feel free to reword; I think the wording should not start with "This package was developed in part..." as I definitely didn't do as much as the main contributors.

[vivarose]

Oh yes, I should acknowledge: I am funded by Hamilton College.

[freemansw1]

Thanks for including me. ORCID looks right. For the funding statement, please use:
"Sean Freeman's contributions were supported by INCUS, a NASA Earth Venture Mission, funded by NASA’s Science Mission Directorate andmanaged through the Earth System Science Pathfinder Program Office under contract number 80LARC22DA011.​"

A little update:
https://github.com/horowitz-lab/Trackpy_GUI is now publicly accessible. It is a GUI and workflow facilitator for TrackPy created by three Hamilton College students as part of their senior thesis project.
