Zstandard

Select Zstandard with Compression.zstd(); Decompressor detects it from its magic number. It requires com.github.luben:zstd-jni at runtime; see Additional Formats.

The one option, level, defaults to 3.

Decompressor enforces the default limits; a stream that expands past a ratio of 100 after the first MiB throws LimitExceededException.
