Dynamic Crosshair doesn't work with Ok Zoomer 1.21.1

[EnnuiL]

Hi, on investigating Up-Mods/OkZoomer#176, I have noticed that this mod's Hide Crosshair feature is incompatible with Dynamic Crosshair on 1.21.1. While we figured out a way to fix this issue for newer versions, I've been stumped on exactly how this issue should be approached

I can take a better look at this later, but from a glance, this looks way trickier than the 1.21.6+ approach
