zstd: updated to 1.3.6

Zstandard v1.3.6 release is focused on intensive dictionary compression for \ 
database scenarios.

This is a new environment we are experimenting. The success of dictionary \ 
compression on small data, of which databases tend to store plentiful, led to \ 
increased adoption, and we now see scenarios where literally thousands of \ 
dictionaries are being used simultaneously, with permanent generation or update \ 
of new dictionaries.
