Saml-reader

Fix web app for updates to dash.

The only change between 0.0.4 and 0.0.5 is that 0.0.5 includes dependency version limiting so that the web app will continue to function, until such a time as I get around to upgrading to more modern versions of dash and Flask.

*New features*:
- SAML Reader now has a new web interface! Please see the readme for information on how to start it up.
- Add ability to check for signing certificate validity by checking the expiration shown in MongoDB Cloud against the public certificate sent in the SAML response.
- Remove tests that check for `email` attribute, as it is no longer required.
- Bug fixes and QOL updates.

*Breaking changes*:
- None

*Major code hygiene changes*:
- None

**Full Changelog**: https://github.com/clegaspi/saml_reader/compare/0.0.3...0.0.4

*New features*:
- Add support for `memberOf`
- Bug fixes

*Breaking changes*:
- Comparison JSON file format has some new fields and a change to the format of `domains`

*Major code hygiene changes*:
- MongoDB Cloud verification done using a graph traversal model of tests instead of a massive validation function. This should encapsulate and abstract this, even if it makes it a bit less readable (although a massive function will get unwieldy too).
- A lot more compartmentalization of code and functionality
I promise to write tests for the next release. In fact, that should be all that is in the next release, along with any changes for bugs/deficiencies that the tests highlight.

- Added multiple parsers, including regex parser, to make reading data more resilient (5)
- Add checks for verified domain (7)
- More sophisticated error catching and messaging (4)
- Logic changes to make this more extensible (hopefully)
