Fix an extremely rare issue where loop point goes outside track bounds if loop end is not defined (#748)

* Fix an incredibly edge-case loop end issue where the loop end is outside track boundaries somehow

* WIP-AB Cleanup and incorrect loop bugfix

Cleanup AB-Loop code
* Someone has to check if AB loop works properly still cause I have no idea how this shit works and the code prior was unreadable.
Don't blame me, blame whoever left this code undocumented like the hag they are.

* Increase max-sample we can accept in the AB loop

Also change conversion to UInt. If someone adds a bad value, it will just return 0, which I guess is fair.
