Subject: [PATCH] Fix a long time ping cause app crash

UInt16(65536) cause app crash:
```
SwiftyPing.swift 362:
let icmpPackage = try self.createICMPPackage(identifier: UInt16(self.identifier), sequenceNumber: UInt16(self.sequenceIndex))
```
when the sequenceIndex keep plus up to Int.max > 65535 :
```
private func incrementSequenceIndex() {
        // Handle overflow gracefully
        if sequenceIndex >= Int.max {
            sequenceIndex = 0
        } else {
            sequenceIndex += 1
        }
    }
```
we can fix it to set the max of sequenceIndex to UInt16.max
