Declare apiGet() and apiPost() protected instead of private

[Fluxlicious]

CcvOnlinePaymentsApi doesn't has a full implementation of the API (e.g. Cancel is missing).
I'd like to extend the base CcvOnlinePaymentsApi and add some methods we need, but extending it right now is not useful because the methods apiGet and apiPost are private.

I'd need this as well
eg The PaymentStatus class is missing data from the original response
only 'amount', 'status', 'failureCode' and 'type' are present in the class, while the response contains a lot more info

currently there is no way to even extend this and use the apiGet(), apiPost(),...
