LGTM
Just minor observation:
why

	var (
		err   error
		algo  compress.CompressionAlgorithm
		level compress.CompressionLevel
	)
	algo, err = algo.FromString(conf.GetString("Compressor.algorithm", "zstd"))
	if err != nil {
		return nil, fmt.Errorf("invalid compressor algorithm: %w", err)
	}
	level, err = level.FromString(conf.GetString("Compressor.level", "default"))
	if err != nil {
		return nil, fmt.Errorf("invalid compressor level: %w", err)
	}

instead of the usual

        var err error
	algo, err = compress.NewCompressionAlgorithm(conf.GetString("Compressor.algorithm", "zstd"))
	if err != nil {
		return nil, fmt.Errorf("invalid compressor algorithm: %w", err)
	}
	level, err = compress.NewCompressionLevel(conf.GetString("Compressor.level", "default"))
	if err != nil {
		return nil, fmt.Errorf("invalid compressor level: %w", err)
	}
