v3.6.0 for UE4.25

Update to get plug working with Unreal 4.25.
From the changelog.md file:

Version 3.6.0

1. Now supports Unreal 4.25. Tracking tested for HMD based hand tracking. However, desktop mode hand tracking still has some bugs/performance issues.
2. Improved performance/stability (due to LeapC.dll change / use of the FastTrack Animation System for Hands).
3. Non-frame based gesture detection system introduced (this reduces the frequency of grabs/pinches dropping out by giving it a buffer time). The old frame based system is still supported through a UI option.
4. Removed some unsupported platforms.
5. Fixed a bug that forced desktop mode when vr headset is attached.
6. Fixed freeing of device property before it is read causing invalid serials/devices.
7. Fixed a bug where HMDPositionOffset and HMDRotationOffset settings for a Vive were being applied to all SteamVR headsets (Valve Index, Varjo, etc), if the value were set to zero - UNREAL-64
8. Fixed bad event usage example.
9. Updated hand colliders to be more accurate (now mesh based).
10. Resolved an issue where performance would decrease after a leap was unplugged/replugged.
11. Fixed a bug where the HMDPositionOffset was being applied twice, and at different scales. Should be in leap units - mm (UNREAL-63)
