Extends cryptoPriceLabel with an icon corresponding to the symbol of the purchase crypto that will appear to the left of the price label. See the docstring for getCryptoPixbuf for details about how this icon is retrieved. Note that automatic icon retrieval requires a coinmarketcap api key to be set at taffybar startup. As with cryptoPriceLabel, this function must be invoked with a type application with the type string that expresses the symbol of the relevant token and the underlying currency in which its price should be expressed. See the docstring of cryptoPriceLabel for details about the exact format that this string should take.

Set the coinmarketcap.com api key that will be used for retrieving crypto icons that are not cached. This should occur before any attempts to retrieve crypto icons happen. The easiest way to call this appropriately is to set it as a startupHook.

Build a label that will reflect the price of some token in some currency in the coingecko API. This function accepts these valuesas a type parameter with kind Value of the form `(symbol for asset being purchased)-(currency the price should be expressed in)`. For example, the product string for the price of bitcoin quoted in U.S. dollars is "BTC-USD". You can invoke this function by enabling the TypeApplications language extension and passing the string associated with the asset that you want to track as follows:

cryptoPriceLabel @"BTC-USD"

If a file is not found there and an an api key for coinmarketcap.com has been set using setCMCAPIKey, an icon will be automatically be retrieved from coinmarketcap.com.
