Duplicate voice files

We were notified that the following voice files are duplicated in the matsuribayashi scripts, which is probably an error.

Note that some duplicates are already fixed (comitted to this repo), but not in the latest release. Those are not included below.

Most likely we just need to delete the second voice line in all these cases, but each should be checked individually.

> I put hacked a couple shell scripts together to search for more dupes in matsuribayashi. Here are the significant ones I found (that we haven't already fixed):

The issue lists specific duplicated voice file references in script files like _mats_014.txt and _kakera08.txt. Start by locating these files in the repository, likely under a scripts or similar directory. For each listed duplicate, examine the context lines to verify the duplication and decide whether to delete the second voice line. Check if any recent commits have already addressed some of these. Testing involves ensuring the game still runs correctly after edits.
