Add my ORCID and affiliation

[leouieda]

The authorship guidelines introduced in fatiando/community#13 specify
that authors on Zenodo archives will be taken from the AUTHORS.md file
and need to have full names, affiliation, and ORCIDs (optionally)
included in that file.

Reminders

• Run make format and make check to make sure the code follows the style guide.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Add new public functions/methods/classes to doc/api/index.rst.
• Write detailed docstrings for all functions/methods.
• If adding new functionality, add an example to the docstring, gallery, and/or tutorials.
