Unsupported NASCAR Style SAFER Barrier and Catchfence 1.22

Hello again! This is an update I've been wanting to do for a while, but I've been on vacation for a week so I wasn't able to do it. Until today.

Changes in this update:
1. Fixed getting stuck inside the SAFER barrier (hopefully)! It also now absorbs the impact in a very realistic way. I did this by completely redoing the way the barrier absorbs impacts, and now it actually does its job (lol)
2. Changed up the proportions of the model to better reflect real walls (SAFER barrier now protrudes more!)
3. Changes in the JBeam to perform much more realistically during lower-speed impacts (this is for you, CrashMandjaro!)
4. Minor tweaks and bug fixes here and there! The changes in this update aid in stability, performance, and realism!

Hope you enjoy!
