Refactor: Improve exception message for required query params

[sorndotdev]

Currently, the error only reports one missing query parameter at a time. Ideally, it should list all missing required parameters.

• 'symbol' is a required query param ...
• 'symbol' and 'date' are required query params ...
• 'symbol', 'date' and 'limit' are required query params ...

I don't see anything going on for a while. @sorndotdev, if you are coming back and keep the project going, I am happy to contribute.

@andyyngo got it - I was offline traveling for a bit, but I’m back now.

It’s a long-term project for me; version 0.3.0 just went out yesterday.
