al_hide_mouse_cursor is missing from allegro-sys

So i was looking on a way to hide the cursor in the allegro docs, found al_hide_mouse_cursor, tried looking for something similar in the rust wrapper, couldn't find it, so i looked at the allegro-sys crate, and couldn't even find it there, tried adding it manually in the mouse.rs file then using that local version of the sys crate but because it doesn't allow me to use the returned pointer from the allegro wrapper because it's a "different version of the crate" it required me to change allegro and the other addons to local versions as well, it's really messy that i had to do all of that just for a missing method

Yeah, aside from merging everything into one crate as #15 suggests you basically need to switch all the interdependent crates to the local versions.
