Contributors

Updating the contributors list contains a bit of a manual process.

Check missing contributors:

all-contributors check

Add a new contributor (see https://allcontributors.org/docs/en/emoji-key for reference):

all-contributors add <username> <contributions>

Regenerate the contributors list:

all-contributors generate

Then, copy the generated list html from CONTRIBUTORS.md to the README.rst file, with proper indentation in .. raw:: html block, along with the badge at the top.
