Add new ZST compression plugin

[asvinours]

I added a new compression plugin based on facebook zstandard compression system.

zstandard offers faster and better compression then gzip

$ time zstd -f -5 random.log -o random.log.zst
Compressed 179309772 bytes into 21463467 bytes ==> 11.97%                      

real    0m1.584s
user    0m0.408s
sys     0m1.072s

$ time lzop -qf1 -o random.log.lzo random.log

real    0m0.387s
user    0m0.304s
sys     0m0.068s

$ time gzip -c random.log > random.log.gz

real    0m3.224s
user    0m2.916s
sys     0m0.180s

$ ls -lh
172M Sep  1 13:43 random.log
49M Sep  1 13:43 random.log.lzo
31M Sep  1 18:58 random.log.gz
21M Sep  1 18:57 random.log.zst

Do other users still want this compression?
Zst is now widely used so bundle it is reasonable.
