Honkai Impact: Find musics reliably

[alexpado]

This is a follow up of #2

PCK files are named differently for Honkai Impact compared to both Genshin Impact and Honkai Star Rail, which make writing the file filter more complicated than it should be.

For Genshin Impact and Honkai Star Rail, all musics (or at least, most of them), are in PCK files named Minimum.pck and MusicX.pck (where X is a number). These files aren't present in Honkai Impact folder.

After extracting few files, it seems that musics are present in file where the name contains _Default, but I have few issues with that:

• Yes it contains music, but not mostly music for a lot of them
• Some of them even contains few musics compared to the total amount of sounds contained in the PCK file...

Leading to the conclusion:

Extracting Honkai Impact 3rd files takes time, a lot of disk space and isn't efficient (over 57 000 files)

I though about filtering by size, but the issue is that there are few musics being shorter than SFX, making their file size smaller than the SFX one at the same time...

Filtering them by name is also a no-go, as the complexity added in the code would be insane for what we gain from it.
