initPaymentSheet params accept payment button label

[tony-schumacher]

Is your feature request related to a problem? Please describe. The payment sheet button is is labelled: "Pay $xxx". Calling the cta "Pay" is sometimes not applicable (fund, deposit, donate etc.).

Describe the solution you'd like Accept a string as a param in the initPaymentSheet() method.

Otherwise it is a great module. Thank you
