Download images to Pictures/Bluesky directory on Android

This commit addresses the issue on Android where all images are stored
in DCIM, which people have complained about. Instead, on Android, it now
saves to `Pictures/Bluesky`, by using react-native-blob-util
(https://github.com/RonRadtke/react-native-blob-util), which is a more
updated fork of rn-fetch-blob.
