Provide a way to override `alternativeAdvertisingNameEnabled`

[Don Juan Javier]

Hello!

Awesome lib. I have a quick question:

The library IOS-Pods-DFU-Library has this option to turn off alternativeAdvertisingNameEnabled:

• https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library/blob/master/iOSDFULibrary/Classes/Implementation/DFUServiceInitiator.swift#L191

Would it be possible to add this as an option when calling NordicDFU.startDFU?

If I'm reading this correctly, it would be easy enough to set the instantiated DFUServiceInitiator class properties here?

I'm curious if the following would work? If so I'll submit a PR:

RCT_EXPORT_METHOD(startDFU:(NSString *)deviceAddress
                  deviceName:(NSString *)deviceName
                  filePath:(NSString *)filePath
                  resolver:(RCTPromiseResolveBlock)resolve
                  rejecter:(RCTPromiseRejectBlock)reject
                  // new param:
                  alternativeAdvertisingNameEnabled:(BOOL *)alternativeAdvertisingNameEnabled)
{
  ...
  initiator.alternativeAdvertisingNameEnabled = alternativeAdvertisingNameEnabled
  ...
}

Forgive me if any of my syntax is off - I'm new to Objective C. :)
