Bug fixes, more transformers, more calibrators, support for more RDP mechanisms

Bug fixes, more transformers, more calibrators, support for more RDP mechanisms. It also fixes the issues of the current pip install version.

Improved calibrator functionality and support for more mechanisms

A few changes that improves the usability and coverage of autodp:

1. Some additions to the autodp_core.Mechanism class so as to support easier implementation of a class using autodp mechanism API. See the example: https://github.com/yuxiangw/autodp/blob/3d28a057d042b51ef69d00a73f46f0db2b44066a/example/example_calibrator.py#L67
2. Adding some classical mechanisms to the mechanism zoo, including the improved analysis for the exponential mechanism by Durfee and Rogers.

New "mechanism" API and new features

1. Object oriented design: see check out autodp_core.py
2. Zoos are open with many private animals: mechanism_zoo, transformer_zoo, calibrator_zoo.
3. Added support for f-DP and privacy profile alongside RDP.
4. Stronger RDP to (eps,delta)-DP conversion.
5. Privacy amplification by X.
6. Exactly tight privacy accounting for Gaussian mechanisms and their compositions.
7. Interpretable privacy guarantee via Hypothesis testing interpretation for any Mechanism.
