Uniswappy

- Introduced a Join abstract interface for Uniswap V2/V3
- Indexing equations R&D and implementation for Uniswap V3
- Abstract interfaces for Uniswap V3

- Now includes Uniswap V3 python refactor
- Accessible via [primitive API](https://defipy.readthedocs.io/en/latest/uniswapv3.html)
- See notebook (uniswap_v3.ipynb) for example

- Improved interface to include ExchangeData object to be passed into LP factories
- Inclusion of quant terminal using 0x API; see [live dashboard](https://dashboard.defipy.org), or run local as local server
- Docs at defipy.org

Minor bug Fix on how Factory and SimpleLPSimulation calls class objects

Added SimpleLPSimulation class
- This object performs an LP simulation using a Geometric Brownian Motion (GBM) process
- Can pull price, and reserve data; can be augmented so that additional data from LP can be harvested during sim trial

Initial release of UniswapPy python package for modelling Uniswap V2 using Python; special features include
- Abstracted Actions: Obfuscation is removed from standard Uniswap action events to help streamline analysis and lower line count
- Rebasing: Can calculate settlment LP token amounts given token amounts and vice versa
- Simulation: Can simulate trading using Geometric Brownian Motion (GBM) process, or feed in actual raw price data to analyze behavior
- Randomized Events: Token amount and time delta models to simulate possible trading behavior
- Revenue Tools: Basic yeild calculators and risk tools to assist in analyzing outcomes
