TORAX tasks now ported to GitHub

[jcitrin]

Many of our internal TORAX tasks have now been ported to GitHub issues for increased visibility and transparency on the feature roadmap.

For increased coordination, we will try and signal which issues are being actively worked on through the assignment feature. However it is fluid.

Please feel free to discuss on the issues, assign any issues to yourselves, and add any issues needed for your specific use-cases.
