download-raise-errors: Add raise_errors and raises to download()

[JTarball]

download() has no raise_errors flag which seems like an oversight

#1832

I have added 'raise_errors' and 'raises' if you need granular exception raises e.g. only the rate limiting exception

[ValueRaider]

What happens when two different tickers throw different exceptions?

[JTarball]

Should raise them separately

In this example test raises=[YFException] which is the base exception .. so all are raised.

Note it will still logger the error also, I assume thats ok.

e.g.

• YFPricesMissingError**: $EGS745W1C011.CA
• YFTzMissingError**: $9519.SR:

@ValueRaider anything else you need from me?

I've pushed a commit that I think make sense, helps with many errors (imagine 10s-100s). Try it:

yf.download(tkrs, raise_errors=True)
yf.download(tkrs, raise_errors='one')
