Found the latest edition. **This is terminal for a USKFetcherCallback**. It isn't for a USKCallback subscription.

Specified by:

onFoundEdition in interface USKCallback

Parameters:

l - The edition number.

key - The key.

newKnownGood - If the highest known good edition (which has actually been fetched with what it pointed to) has increased. Otherwise, the highest known SSK slot has been increased, from which searches will start, but we do not know whether it can actually be fetched successfully.

newSlotToo - If newKnownGood is set, this indicates whether it is also a new highest known SSK slot. If newKnownGood is not set, there is always a new highest known SSK slot.
