stock_screener added to company_valuation

In this release, I have added the stock screener.

Stocks can be screened with 5 criteria, namely, market cap, beta, dividend, average volume, and sector. An additional input allows you to specify the maximum number of stocks returned per query.

use the following function arguments, which are None by default. All inputs are in 'int'/'float' form except for sector, which is in the 'string' format.

The following sectors are identified by the fmpcloud.io API:

"Basic Materials" ,
"Communication Services" ,
"Consumer Cyclical" ,
"Consumer Defensive" ,
"Energy" ,
"Financial" ,
"Financial Services" ,
"Healthcare" ,
"Industrial Goods" ,
"Industrials" ,
"Real Estate" ,
"Technology" ,
"Utilities"

Enjoy
