Mne-faster

Did some maintenance on the code:

- moved from `setup.py` to using `pyproject.toml`
- format all code with BLACK
- setup Github CI pipeline to run the unit tests on every push
- fix version string (thanks larsoner)

* Update imports to be compatible with modern MNE-Python.
* Use `pytest` instead of `nose` for testing
* Formatting with Black

Changes:

- Updated the example and `run_faster` to use the modern `mne.preprocessing.ICA` interface of MNE-Python.
- Updated the example and `run_faster` to use the new `set_eeg_reference` function of MNE-Python.
- MNE-faster is now compatible with MNE-Python version 1.0
