This update primarily contains large processor updates, with various bug fixes and import error fixes.
A new CLI command is also added. Now, `python pupil_lib.py` is replaced with `pupillib`.
After running `python setup.py install`, run `pupillib --help` to test it out.
With these changes, it also brings us to the first post-beta release of the library as the majority of the functionality is ready to be used.
