Motivation: we need to keep the two values together in order to know how much to delay by (based on what rywToken is newest)

Motivation: it's unclear from the previous method name that we are expecting something to be returned.

Motivation: make use of the new object to pull out the `rywDelay` value & delay by that amount.

By doing so we help minimize the number of retries that will hit the backend.

Motivation: update all usages of `rywToken` to now make use of the new `RywData` object.

In `ConsistencyManager` we also renamed the method `setRywToken` to `setRywData`

Motivation: we switched to return a RywData object so method name didn't make sense any more

Motivation: add clarity on why the method maxOrNull (which uses lexicographic evaulation for strings) works for this use case.

…ject

Motivation: rywData shouldn't be considered a valid rywData object if rywToken is undefined.

We update usage across the board to account for this type change.
