Overwrite data with the same name as the same type

[ColinCollins]

Hi, developers of 'localization', I'm a typedoc user. recently, I start to use the 'localization' plugin to generate the different version docs, but I find your plugin has a defect in the convert feature.
Just like what I described on the issue title. For example, I have two files in the same path, and both of them contain an enum named D, then one of them will lose data.
Hope you can improve the convert feature。

This is the bug location and I get a property undefined when I use it
