Description

This PR fixes an issue when performing file requests with the Accept-Encoding: zstd header and getting an incorrect Content-Encoding header value for Zstd files if enabling the compression-static feature.

Then incorrect Content-Encoding header value was zst (extension) rather than zstd (encoding).

Fixes #451
