SyncReorgManagerwhich is triggered at each successful batch import.SyncReorgManagerwill call a protoarray'sreorgWhileSyncing(via ForkChoiceTrigger->ForkChoice) which will "switch" votes from the old chain to the new chain. This logic only applies to protoarray in "syncing state" (no votes applied)It is designed to reorg only if we import a block at a more recent slot than our current head (+ 10 slot).
There could be use-cases in which we want to reorg sooner: if our DB contains a long non-canonical chain we will keep the tip of that as our canonical head until the contending chain we are syncing overcome that tip.
But for now this implementation solves the problem in which our chain tip is just on a reorged block and we just keep syncing from its parent.
