Shhhhh, don't tell anyone but I stumbled on a bug with the 
authentication of the AlphaVantage API Key. Make one up!

Using "NOTAREALAPIKEY" as the key, I found that lookups work. I hit on 
this when testing updates to the AlphaVantage.pm module to see what is 
returned for invalid as well as blank/unset key.

curl 
'https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=NXPI&interval=5min&apikey=NOTAREALAPIKEY'

I sent AlphaVantage an email about this last year and never got a 
response, nor did the issue get fixed.

In related news, I am just about finished testing a new currency module 
for Finance::Quote that gets the data from Yahoo. No API key needed.

Along with this I am thinking about using an environment variable 
(FQ_CURRENCY) to allow users to choose their preferred currency exchange 
API. If not set a default will be used, currently AlphaVantage, but that 
may change to YahooJSON so users will not have to worry about setting 
both it and an AV API key. Feel free to discuss this at 
https://github.com/finance-quote/finance-quote/discussions/239.
