Update: reimplement spectating to use ISubscriptionStrategy instead of secondary groups - Done via SpectatorSubStrategy (takes subscriptions of target) and SpectatedSubStrategy (notifies when group changes) - Removed old secondary group code and reverted relevant Network API changes - Made Networkable.OnSubscriptionChange public This also fixes the bug with previous version that it only saw "near" distance entities Tests: Spectated player on craggy, flew around until island disappeared from rendering - no NREs. Got 2 things to improve, and I think it's done
