[Feature Request] Ability to adjust song playback speed with ReLoader

[Mawntee]

Would be extremely handy to have some keybinds [eg. +-] to incrementally adjust the current playback speed of a map on the fly without needing to back out. I know there's a few other mods like Naluluna's Rewinder or Practice Plugin that already do this from the pause menu, but those have scrubbing features as well which break just about every custom event in a Chroma or Noodle map
