NiGHTS drone loop: Change flyangle comparison to fix detection from vertical angles

Use > 90 && < 270 instead of >= 90 && <= 270. Fixes a bug where if you fly directly up (flyangle 90) or directly down (flyangle 270), that registers as a backwards direction, so you trigger the loop detection by flying BACKWARDS, not FORWARDS. This edge case (only possible via JUMPTOAXIS) should default to FORWARDS looping.
