Gzip file not automatically uncompressed on iOS

When downloading a gzip file with a response containing `Content-Encoding=gzip`, the file is uncompressed automatically on Android.
However, that does not seem to be the case on iOS.
On iOS, when trying to read the file as String I was receiving the following error: `Failed to decode data using encoding 'utf-8'`.
After manually using `GZipCodec.deocode()` on the file bytes I was able to read it.

**To Reproduce**

Steps to reproduce the behavior:

1. Enqueue download task for a gzip file on Android and iOS
2. Attempt to read using `File().readAsString` after file finishes with DownloadStatusResult.complete
3. Observe file contents on Android, and `Failed to decode data using encoding 'utf-8'` on iOS.

**Expected behavior**
autoUncompress to apply to downloaded gzip files across platforms.
