Some changes to the Discord Bot

FLOW COMMANDS REWORKED

-Flow commands (/smallflow, /flow, /bigflow) have been merged into a singular command /flow_ticker

-The /flow command has been reworked so that it allows a search of all tickers (minus index/ETF tickers)

-Old flow commands will redirect users to the new commands

NEW FUNCTIONALITY

-Premium users can use /watchlist flow_ticker to pull up the result for /flow_ticker for all watchlisted tickers
