Checklist:

• _Was this PR discussed in an issue? _ Closes issue Copyright headers and contributors list #486

This PR is simply to add a Copyright notice everywhere, and update the LICENSE file. There's a lot of changes but it's quite simple. I'm tagging lots of reviewers for visibility.

About 90-95% of the file headers are:

"""
--------------------------------------------------------------------------------
Copyright (c) 2023 Valence Labs, Recursion Pharmaceuticals and Graphcore Limited.

Use of this software is subject to the terms and conditions outlined in the LICENSE file.
Unauthorized modification, distribution, or use is prohibited. Provided 'as is' without
warranties of any kind.

Valence Labs, Recursion Pharmaceuticals and Graphcore Limited are not liable
for any damages arising from its use. Refer to the LICENSE file for the full terms and conditions.
--------------------------------------------------------------------------------
"""

With 2 .sh files modified to attribute only to Graphcore and ~10 .py files modified to attribute only to Valence. To be safe, every file that was modified between 5 and 18 months ago were attributed to everyone.

I also listed the most important Academic collaborators in the LICENSE file
