Added a dialog tab to easily access the "ABNK" tab

Additionally, I fixed a bug where audio files (ASND) could only play once, and once played, downloading them would return an empty file.

On another note, I noticed that the sound files being downloaded include the "File head" and "chunk head" header (the first few bytes includes something like PF�����ASNDASND)

mp3 is a fairly resilient format as players will attempt to find a specific magic header in the file and start from there, but it may be nice to clean this up.

I also noticed that some sounds couldn't play, which I assume is due to some compression as I haven't encountered this sound in game (from https://wiki.guildwars2.com/wiki/Gw2.dat).

Do you know if the library provides an easy way to decompress these?

One thing that also came to mind is that we could in theory have the renderer extract the data, put it in a blob, generate a URL, and pass that URL to an audio tag. This would add a player with a progress bar and a button to download automatically.

We could even have some "autoplay sound" checkbox.

In order to do this, we'd need some kind of callback to remove the blob URL when another object is loaded, to avoid memory leaks. Do you know if this mechanism already exists ?

Hello 👋
Thanks for your contribution. I wasn't active on Guildwars2 anymore during the after EoD / SoTO period, which explain the lack of answer/activity.

For your PR, I'd probably extract the two parts (the ASND fix and the ABNK changes) in different two different PRs.

Concerning the question about the sound files, ABNK is I think the only chunk containing a nested PF file. These are like ASND files inside the ABNK file. The current implementation doesn't support parsing nested files, but I wouldn't expect it to be a very difficult change. It must happen inside the library though, I'll check it later.
