tobac v1.3.1 Release

[sean.f...@colostate.edu]

Hi tobac users, 

We are pleased to announce the release of tobac v1.3.1 today. While v1.3.1 is a bugfix release, some of you may not have seen the v1.3.0 release, which included some substantial optimizations to the tracking and feature detection algorithms, so I've included the release notes on both at the bottom of this email. 

The tobac repository (and associated projects) have been moved to a new overarching organization on GitHub: https://github.com/tobac-project/. This new organization includes the main tobac repository, the tutorial repositories, and any future tobac package-associated repositories. 

To update to tobac v1.3.1, you can `conda update -c conda-forge tobac`, or whatever is appropriate for your package manager. Development continues on v1.3.2, v1.4, v1.5, and beyond. Feel free to join the development efforts on the GitHub here: https://github.com/tobac-project/tobac
