Twinb Shotgun Animation Tweaks

Small tweaks to the twin-b shotgun's animations.

• Added non-empty reload animation.
• Added shell ejection particle when reloading.
• Added small camera shake to draw animation.
• Added jump and land animations.
• Added silencer support. Not like it really matters since you can't use it in a real match but i thought it would be neat.
• Edited the 'ads to ads-onehanded' animation so the gun always stays in the center of the screen.
• No longer uses one-handed animations when sliding.

More detailed showcases of these changes can be seen on this mod's thread in the Northstar discord server.
