Converts iOS implementation from Objective-c to Swift
# During the conversion process some updates to the code structure were also made
- Modularize codebase from single file to smaller focused files
- Untangled large nested IF statements
- Added more null checks, since Swift is more strict with null pointers
- Added property to allow for decoding of local video sources with self contained key for offline playback
- Updates example apps to test react-native 0.63.4 and uses auto native dependency imports for android and ios
Latest Xcode 12 fails to build while without a module to depend on React-Core directly hence this change is necessary for native modules on iOS. This change requires to React Native 0.60.2 or newer. For more details please check: facebook/react-native#29633 (comment)
This PR adds support for DRM streams on iOS (Fairplay) and Android (Playready, Widevine, Clearkey)
I am neither Android nor iOS developer, so feel free to provide feedback to improve this PR.
**Test stream for ANDROID:**
```
testStream = {
uri: 'http://profficialsite.origin.mediaservices.windows.net/c51358ea-9a5e-4322-8951-897d640fdfd7/tearsofsteel_4k.ism/manifest(format=mpd-time-csf)',
type: 'mpd',
drm: {
type: DRMType.PLAYREADY,
licenseServer: 'http://test.playready.microsoft.com/service/rightsmanager.asmx?cfg=(persist:false,sl:150)'
}
};
```
or
```
{
uri: 'https://media.axprod.net/TestVectors/v7-MultiDRM-SingleKey/Manifest_1080p.mpd',
drm: {
type: 'widevine', //or DRMType.WIDEVINE

}
}
```
**Test stream for iOS:**
Sorry but I can not provide free streams to test. If anyone can provide test streams, or found some we can use, please let me know to also test them.
It has been tested with a private provider and they work, at least with the `getLicense` override method. (An example implementation is provided in the README)
