Doesn't work for exports in different languages

I don't programme in Python, but I approximately understood what is going on in the script.

I see, that you detect if the message contains a media file by searching for the `(file attached)` string (lines 74 and 76). The problem is, that when you export WhatsApp chat with different localisation settings, this string is different. For example, in my language, it says `(soubor byl přiložen)` instead.

Would it be possible to add a dictionary file (INI perhaps) and a selection of the export language to solve this problem? Eventually, instead of the dictionary file, there could be a direct input field for that string, but it might be slightly more difficult for some less tech-savvy people use the application.
