Add More EQ Bands

And one more, the difference here being a request for higher frequencies:

@zRed

I see many users asking for control over lower frequencies, but today I was listening to “vampire” by Olivia Rodrigo, and at the beginning of the song I could hear a very high-pitched buzzing noise, likely due to the post-processing increasing intensity in the 7KHz - 20KHz range to make it sound better and clearer, but they probably overdid it and now there’s a buzzing noise. Adjusting the 16KHz band does reduce the buzzing but makes the voice feel duller, I’m pretty sure the buzzing is over 16KHz and it’d be really nice if I could isolate that band without affecting the voice too much.
Thanks for developing this btw, I really love this program, as soon as I downloaded it, it felt like I bought a new pair of expensive headphones but mine are like 4-5 years old, I’ll certainly consider a donation when I get the chance
