v2.0.2 ios setScanRegion crashes the app.

I managed to debug the problem and the directions from region are doubles instead of int.
Foundation/NSNumber.swift:384: Fatal error: Unable to bridge NSNumber to Int

 let region = call.getObject("region")
 self.scanRegion = ScanRegion()
 self.scanRegion.top = region?["top"] as! Int

I temporarily fix it like this:

 if let region = call.getObject("region") as? [String: Any] {
          self.scanRegion = ScanRegion()
          self.scanRegion.top = Int(region["top"] as? Double ?? 0.0)
          self.scanRegion.right = Int(region["right"] as? Double ?? 0.0)
          self.scanRegion.left = Int(region["left"] as? Double ?? 0.0)
          self.scanRegion.bottom = Int(region["bottom"] as? Double ?? 0.0)
          self.scanRegion.measuredByPercentage = Int(region["measuredByPercentage"] as? Double ?? 0.0)
      }

You have to pass an integer in the JS side.

I'll put rounding on the JS side and test it out, but wouldn't it be better if it was also handled on the swift side to avoid errors?

Right. PRs are welcome.
