Subject: [PATCH] applets: stub mii selector to always return a standard mii

To obtain the data, the LLEd mii selector of system version 11.8.0 was used.
In AppletManager::GlanceParameter, the following code was added to write the returned buffer data to a file:

    if (parameter.buffer.size() == 132) {
        std::u16string name(10, '\0');
        std::memcpy(name.data(), parameter.buffer.data() + 0x26, 10 * sizeof(u16));
        name = std::u16string(name.data());
        FileUtil::IOFile file{fmt::format("{}.mii", Common::UTF16ToUTF8(name)), "wb"};
        file.WriteBytes(parameter.buffer.data(), parameter.buffer.size());
    }

Then "xxd -i" was used on the file to convert it to a hex array.
