Fixes#315.
This PR aims to address the [recent changes](https://www.blog.google/products/photos/simplifying-google-photos-and-google-drive/) in Google Photos + Google Drive where syncing between the two is no longer supported.
It works by uploading photos as part of the import process to add a copy of every photo in your library to Google Photos. Google Drive is not required for this plugin to work.
This plugin lets you have all your photos in Google Photos without relying on Google Drive. You can use another cloud storage service like iCloud or Dropbox or no cloud storage at all.
- [x] Add tests for `after()` plugin methods.
- [x] Add support for storage/async support.
- [x] Include plugins into code coverage.
- [x] Sweep code and clean up and add comments.
Fixes#281 and #269
When elodie imports images, imghdr.what is used to determine the image
type. imghdr implementation won't support all JPEG variants. Because
of this, even for a valid JPEG file, imghdr.what returns None causing
elodie to skip the image during import.
This commit adds a fallback mechanism which uses PIL(pillow) library to
identify image formats. When imghdr fails, elodie uses pillow to
identify image format. When pillow is unavailable, it will be treated as
an invalid media file. Pillow is imported only when imghdr fails.
