Subject: [PATCH] Enhanced analog cam behavior when spike rolling or in a deku
 flower (#306)

* 279 Adjusted autocam/analog cam behavior while inside of a deku flower or when spike rolling

* override analog cam while left stick is active in deku flower

* Change to auto cam when spike rolling (#323)

* Fix duplicate skip_analog_cam_once declaration
