Add default currency code or update docs

[Raphtor]

For some reason, I am getting the error

{'base': ['Currency code Splitwise does not support the given currency code']}

When trying to create an expense without explicitly setting the currency code. Previously this was not an issue, and I suspect something changed in the Splitwise API.

As of right now, the splitwise documentation at https://dev.splitwise.com/#tag/expenses/paths/~1create_expense/post does not mark the currency_code field as required. Image below of the documentation taken just now

I am running into the same error and failing to create an expense. Will try to add currency code and update later

Adding e.setCurrencyCode("EUR") in my code made the request go through, now the expense shows up on the Splitwise app on my phone.

+1 on official and SDK's documentation being outdated

Fixed in v3.0.0
