I've imported zstd because thats the way the rest of the decompressors are 

We could potentially use libzstd as an external dependency, since its only 
dependency is libc
and GRUB provides the definitions of the libc functions that zstd needs to 
(memcpy, and memmove). Theres some other stuff in the library that requires 
libc functionality
that GRUB doesn't provide, but that isn't used during decompression. We strip 
those files
out in the import.

Let me know if you want me to switch to an external dependency.
