Zstandard v1.5.2

Zstandard v1.5.2 is a bug-fix release, addressing issues that were raised with the v1.5.1 release.

In particular, as a side-effect of the inclusion of assembly code in our source tree, binary artifacts were being marked as needing an executable stack on non-amd64 architectures. This release corrects that issue. More context is available in #2963.

This release also corrects a performance regression that was introduced in v1.5.0 that slows down compression of very small data when using the streaming API. Issue #2966 tracks that topic.

In addition there are a number of smaller improvements and fixes.
