Fixes: #1953

This pull request proposes the following changes:

• added an option to deinit and release the LGS/GHub dll
• check if the sdk functions actually succeed
• Aurora starting after LGS/Ghub
• Connection to LGS/GHub lost (program closed/restarted)
• detaching/reattaching a device

Known issues/To do:

• when switching profiles in GHub, Ghub sometimes rejects sdk commands

[Cheerpipe]

Tested with several logitech devies (kb, mice, speakers and mousemat).

It works (randomly) for the keyboard but not for devices that takes more time to be initialized by G HUB.

Test case:

1. Open G HUB
2. Open Aurora

Every is working fine so far

3. Close G HUB

Logitech device stops in Aurora Device Manager

4. Start G HUB Again

Keyboard is synced with Aurora but mouse and mousemat (speakers some time) are out of sync. Maybe because Logitch SDK is re-loaded before G HUB detects all devices.

I rewrote the logitech integration recently (dev branch), it should have this feature in it. If you notice that it does not work correctly, please submit a new pull request. Aurora seems to detect when LGS is closed (since the Set methods return false when that happens). I think that's what you were trying to solve.

Thanks for bringing this issue to my attention.
