barCodeTypes error on iOS

[letops]

Expected behaviour

We should only have to set an array with the barcode types that we wish to detect, as the documentation explains: [ 'aztec', 'code128', ...etc ]

Actual behaviour

This is not respected by iOS. In iOS you need to set the barcode types in a different manner, e.g. [ 'org.iso.Aztec', 'org.iso.Code128', ...etc ], if you don't the app freezes and crashes.

Environment

• React Native version: 0.41.2
• React Native platform + platform version: iOS 10.3

Some other findings

On ANDROID only:

    barCodeTypes = {[
      'aztec',
      'codabar',  // Not in the docs, but found in code
      'code128',
      'code39',
      // 'code39mod43',  // Found in the docs but not in the code
      'code93',
      'datamatrix',  // When available(?), according to the docs
      'ean13',
      'ean8',
      'interleaved2of5',  // When available(?), according to the docs
      // 'itf14',  // When available(?), according to the docs, but not found in code
      'maxicode',  // Not in the docs, but found in code
      'pdf417',
      'qr',
      'rss14',  // Not in the docs, but found in code
      'rssexpanded',  // Not in the docs, but found in code
      'upca',
      'upce',
      'upceanextension',
    ]

On IOS only: (#613 is the only place where this is commented)

    barCodeTypes = {[
        'org.iso.Aztec',
        'org.iso.Code128',
        // 'code138' should be here, but not sure of the namespace (found in code)
        'org.iso.Code39',
        'org.iso.Code39Mod43',
        'com.intermec.Code93',
        // 'datamatrix' should be here, but not sure of the namespace (found in code)
        'org.gs1.EAN-13',
        'org.gs1.EAN-8',
        // 'interleaved2of5' should be here, but not sure of the namespace (found in code)
        // 'itf14' should be here, but not sure of the namespace (found in code)
        'org.iso.PDF417',
        'org.iso.QRCode',
        'org.gs1.UPC-E',
    ]}

On iOS, the string to use for datamatrix is org.iso.DataMatrix (available since iOS8 https://developer.apple.com/documentation/avfoundation/avmetadataobjecttypedatamatrixcode)

Per documentation, this issue should've been resolved by using Camera.constants.barCodeType, but it doesn't work for me. See: #1206

Please test it with the newest version of RNCamera and open a new issue if this error still occurs.
