Major overhaul for hit registration and reducing shooting input delay
The major component of this update is hit registration improvements, this involves things like improving server netcode, improving client accuracy for prediction when you should get a hit, and fixing a myriad of bugs that were found when investigating missed shots. The full patch notes below cover all of the things that were changed.

Another major component of the update is the improvement to gun feel, via large reduction in delay for shooting inputs and feedback. This also improves recoil feel as the clients shots and servers shots are lined up with the recoil timings, allowing for rapid fire to correctly be registered on the server.

Hit Registration and Shooting Improvements:
- Improved server understanding of client prediction for verification of hits to improve hit registration
- Improved client FX/Hitsounds prediction to line up properly with where the client should be predicting the hit
- No rolling back shots - Once a shot has done damage, the damage won't be undone when a high latency players movement is simulated - Players moving before incoming shot packets arrive on the server don't cause shots to be ignored when being simulated
- Clientside shooting delay is now mostly removed, shooting is nearly instant while hit FX/sounds have a slight delay
- Added modifier for multiple hit sounds to make it easier to understand how many hits are made with shotguns
- Added dryfire to client shot prediction, guns will play a dryfire sound when you attempt to fire them while empty
- Fixed bug where clients guns could occasionally have their sights mis-aligned
- Add client shot prediction RNG seeding so that clients can render shots involving RNG at client shooting time correctly (hipfire or brace without laser)
- Recoil is moved to client shooting time to give better recoil timing to resolve feeling with recoil feeling misaligned with fire rate
- Flinches from hits are now predicted as to avoid mis-predictions on double headshots
- Shooting the chambered bullet without a mag loaded is now possible (and displays on the ammo count)
Work that still needs to be done:
With the updates, there are still things that need to be done so we can continue to improve the accuracy of player movement and shooting, but this is a large step forward!
- Improve server extrapolation to smooth out movement for high latency players
- Improve time resolution of shooting to reduce discrepancy between player visuals and player hitboxes used for collision detection
- Update server and client communication to allow more up to date rendering of other players' movement - Increases limb shooting accuracy - Decreases animation judder
Other:
- Fix bug where clients body would change animation and "break" after laying on the ground for five seconds
- Modified home screen
