Catalog doesn't consider series with multi-part seasons

[igorcafe]

Describe the bug

For example, Attack on Titan Season 3 has two parts:

• Part 1: Episode 1 to 12
• Part 2: Episode 1 to 10

But Stremio counts as episodes 1 to 22, and it "breaks" some extensions that searches based on Part 2 Episode 1.

I'm not sure if it's a "bug" in Stremio itself or if its a bug in the extension I'm using, which is Torrent.io.

To Reproduce

1. Install Torrent.io (maybe other extensions can reproduce it)
2. Try to find S03E12 of Attack on Titan from Erai Raws
3. Succeeds
4. Now try to find S03E13 of Attack on Titan from Erai Raws
5. Won't find because its part 2 episode 1

Expected behavior

To find the episode.

Additional context

I tried in Desktop, Web and Mobile latest versions and all reproduce the problem.
