[FEAT] Support Cryptocurrencies

[NeonDaniel]

Objective

Support queries for cryptocurrency values. Alpha Vantage has the data, just need to improve search and intents.

Initial Implementation Requirements

• Resolve requests for "bitcoin" and other crypto currencies

Other Considerations

• What currency are these valued in
• Does this need better disambiguation like CaffeineWiz?

This could also be implemented first as a separate API method to start before working on intent updates
