Stock node2

Abel Asrese requested to merge stock-node2 into main

Completed 2 stock nodes:

Stock History: Input(takes 1 stock ticker as input as string), Output(table). Stock Ticker: Input(takes 1 stock ticker as input as string), Output(int). Change to socket due to a bug due to CORS(https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). Should still work the same.
