To everyone: I've made a few fixes and updates to the package, so please delete and reinstall!

Changelog

   >v1.0 - 30 Apr 2020 
      >Completely overhauled from previous 757 version.
      
   >v1.1 - 01 May 2020
       >Fixed read-me file
      >Tweaked "Drag_rumble" logic so that it only comes on when BOTH side spoilers are at least 30% extended. Before, it was
        only based on one side - which led to a rumble when in a hard bank for spoilers.
       >Disabled gyro sound, was too intense no matter the volume. In the real cockpit it's very drowned out.

   >v1.2 - 02 May 2020
       >Fixed logic error where ADP wouldn't come on for slats extending in the air
     
   >v1.21 - 03 May 2020
       >Fixed gauge error that would arise from a wav file being accidentally left blank (parameter missing error)
     
   >v1.25 - 03 May 2020
       >Fixed logic error where APU start sound would happen with the battery off
