Feat: implement price() method

AlexTheWizardL commented 1 month ago

Limitations and details:

There is no way to receive a history of price changes. The "currency/exchangerate" endpoint is the only one to calculate the exchange rate and it returns only one float value at a time
We can not look up for a custom currency exchange rate. My goal was to test an exchange rate for a created currency. After creating a custom currency using the currency/create.json endpoint and trying to receive its rate from the "currency/exchangerate" endpoint it returns an empty string and doesn't see a new currency
Test action will fail until https://github.com/macxred/cashctrl_api/pull/44 is merged

@lasuk Please review the changes and provide feedback or approval for merging.

Thanks for completing 'price' methods to the extend supported by the CashCtrl API.

I've added a commit to further clarify error messages and docstrings.

Ready for merging as soon as the CI test gives us the green light ..
