From 1bb2ec24b433bf87fed40e207c61c6aa8790e793 Mon Sep 17 00:00:00 2001

Subject: [PATCH] test_write_filter_zstd: size @ lvl=20 < default < lvl=1
Raise compression on the second test to level=20, and perform a
third at level=1. Expect the output archive sizes to line up
based on compression level. Reduces test susceptibility to small
output size variations from different libzstd releases.
