Create a table showing the dates when a stock is listed and delisted

For stocks listed before 1994, set the listing date to be the first date we have price data for that stock

Provide ways to search stocks by ticker and timeframe account for ticker name change

Example: YHOO changed the ticker name to AABA in 2017 which then stopped trading in 2019. Use this as the test case.
