reading progress percentage calculation #102

Brief summary

The percentage for reading progress is rounded to the higher number, which is a problem because if there's a manga with more than 100 chapters, it's marked as done even if there's unread chapters.
The fix would be to simply round to the lower number, but then there could be a issue for 0%, which you can just add a flag if you started reading or not and show the indicator depending of that.

Steps to reproduce

1. Read a manga with a lot of chapters
2. Wait for a new chapter to release
3. The manga is still marked as read despite having new chapters
