Add settings to optimize/decrease sound latency

[Calinou]

OS: Fedora 33
Equalizer version: Git 2659d0f
Sound device: Analog (Sennheiser Game Zero), connected to the motherboard's output jack

When enabling this equalizer plugin, I get significant latency which is noticeable in fast-paced games. Are there any tunables I can use to decrease this latency? When the plugin is disabled, I get lower latency.

I'd be OK with trading higher CPU usage for lower latency.
