FinanceToolkit v2.0.5

As reported by #190, the endpoints used within the Finance Toolkit used a retired version of the FMP API. This led to new API keys not being able to collect any data. I have fixed this issue by changing all endpoints to the stable release. This does mean that the data can be slightly different or certain API calls under the Free plan are more limited.

Furthermore, Option Chains and Implied Volatilty calculations failed. This has now been resolved by using yfinance in these functions.
