[LITE] Old Survivor Animations

Re-adds the good old animations from pre-2021 without altering movement mechanics.
An almost 1:1 recreation of the original "old animations" mod that was available since 2021 until 2024.
Only difference is, this version contains 4 additional custom Blend Spaces to fix crouching animations issues caused by BHVR updating them.
