Add more way to activate crosshair

[mumimoi]

Can you add more way to activate crosshair without only crouch, like in addon setting or new button. Because it will more helpful when we are flying or use elytra and we want to activate it. Thank you!

Maybe I'll try implementing an F8 button for PC users and a flying button or top middle button for mobile users. There will be an option for that in the resource pack.

As for how to activate it, it might be tricky since the crosshair only moves when the paper doll moves as well. This means the crosshair would disappear as soon as the paper doll stops moving.
