[v5.3.1] Adding an option to style the progress in the await_view

[wrozwad]

Is your feature request related to a problem? Please describe.
While we had full control over styling the progress in AdyenCheckout.PaymentInProgressView.ProgressBar, we currently don't have the capability to make any changes to the progress during actions like await, for example, after a BLIK payment:

Describe the solution you'd like
Adding a separate style for the ProgressBar in the await_view layout would allow us to change the size and color of the progress to match the rest of the application consistently.
Additionally, it would be beneficial if you removed android:layout_margin directly from the TextView and instead placed this parameter into the style AdyenCheckout.Await.WaitingConfirmationTextView in the same await_view layout.

Hi @wrozwad, this should be doable but we'll get back to you when we have more concrete information.
