Zepp OS: Refactor file upload, fix notification icons > 56x56px

- File uploads are split in chunks, with the size dictated by the
  watches. There seem to be 2 protocol versions, without any noticeable
  differences
- Extract the file upload logic to a standalone class. This makes it
  easier to keep track of concurrent requests, each of which have their
  own session id
- Icons larger than 8KB will end up split in multiple chunks - we now
  handle that correctly
- Notification icons are also requested in 2 different formats, but
  the actual encoding seems to be the same, with only a different id
