feat: Allow logarithmic amplification

[daalfox]

Adds volume control in decibels discussed in #714

This is my first contribution on this crate. Just checking in with you about the general approach for this. Is it ok?

I understand the choices you made however I think we can do better. Let me know what you think of the feedback.

Further more did you look at the resource Roderick linked in the issue? It features a slightly more involved calculation that leads to a nicer volume curve. We could use that instead or have both the current log and that nicer one.

Yeah I wanted to keep myself in the same page with you. I just skimmed through the article I will check it out. Thanks for review

You can look at the code I linked to, which compresses that article into 10 lines of code. You can copy and/or modify those lines from me under public domain.
