Code isn't updated + CoinMktCap isn't free -> change to CG+AlphaVantage for BTC OHLC bars

[MacroMuppet]

Hey bud. I updated some of the code via my own repo w/o a pull request. https://github.com/jonathansheets517/Demark_trading_indicator.git

If you like it I'll submit a pull

List of things updated changed:

• changed coinmktcap (not free anymore) -> Coingecko+Alpha Vantage for BTC and ETHC OHLC Bars
• added separate create CSV Futures PY file to download historical OHLC futures data for US Treasuries + Gold + Equity Index Futures
• for those that are coding novices and can't get data correctly I updated a PY file to get BTC and ETH and save it to a csv file in their directory.
• Changed some relational tools for arrow size so its not fucked up so much changing from differing assets in price (ie BTC 70,000 vs 10y Treasury future $120

Yea sorry bud. I should note that its not being regularly updated.

The base code for calculating the TD signals is there to rip and throw into whatever projects.

Too cumbersome to keep it updated for two people that would come across it.
