text: Title: Create Daily Sentiment Reader for IEX?
  Body: Hi - all  - an additional reader for IEX for the link below would be great. I tried creating something based on pandas_datareader.iex.daily.IEXDailyReader but couldn't get it to work. Ideally getting a data frame back with daily sentiment between two dates (start, end) would be extremely useful.
  
  Here is the API I'm trying to hit....
  
  https://iexcloud.io/docs/api/#social-sentiment.
  
  Anyone have any suggestions ?
