Add "is not" property to the work

### Problem

### A clear and concise description of what you want to happen
There are a lot of works that might have the same titles, but are actually different works or the other work might be an adaptation of the first.

In case of manga, there are often two editions being published: Tankōbon and Bunkōbon. They have the same content, but different amount of chapters inside them.

- Tankobon is the standard edition
- Bunkobon is the cheaper version with smaller dimensions. And contains more chapters than the Tankobon

So, volume 1 of Tankobon might contain 5 chapters, and Bunkobon would have 10 chapters in the 1st volume. When the series gets fully published there might be 10 Tankobon volumes, but just 5 of Bunkobon. This might cause a confusion when making merges.

Currently, there is nothing preventing these works from merging and the librarian might accidentally do a faulty merge. There is an option of adding into a title info about the format, but I think a property to prevent merge would be a more reliable solution.

I think, this was discussed in some other issues, but no separate one was created.
