Fix: Resolved Obj-C type errors for RN 0.76+

[jakecurreri]

Fix for #22

This resolves the following error on RN 0.76+

 RNNordicDfu.startDFU(): Error while converting JavaScript argument 3 to Objective C type NSInteger. Objective C type NSInteger is unsupported.

The error occurs because the method signature has incorrect parameter types. For packetReceiptNotificationParameter, it's declared as NSInteger * (pointer) when it should be just NSInteger (primitive type). Similarly, alternativeAdvertisingNameEnabled should be BOOL instead of BOOL *.
