expose expiration in RxOAuthManager

[phamtdat]

Hello, will you consider exposing oauthStore.expiresAt (or at least the oauthStore.tokenExpired() function) via a class member in RxOAuthManager? I know that the class already handles expiration internally, but for a specific purpose of my application, I need the expiration time. Or is there a specific reason why expiresAt should not be exposed by RxOAuthManager?

Hello, yep it should not be a problem. You can create a PR for that :) im not sure when I will have time to implement it
