Add refresh token exception hook to list of compliance hooks?

[ramennoodles20]

I have a use case were sometimes my stored users' tokens expire and thus they need to reauthenticate into whatever app I'm trying to request data from.

In these cases I get an error 400 from the api I'm requesting from and simply ask my user to reauthenticate using my usual oAuth2 flow.

Since I don't know exactly when a token will expire my current approach is to wrap every request I make to these apis in a try catch and then handle the exception from there.

I noticed that there are some compliance hooks and was wondering if it would be appropriate to add something like a refresh_token_exception hook to be called if the library runs into an error code while refreshing the token as opposed to just calling the usual refresh_token_response with the raw response.

If this makes sense I would be happy to submit a pull request for it
