ZlibCompressor seems not to respect compression level

Zarr.jl/src/Compressors.jl

Lines 139 to 147 in f436713

	function zuncompress(a, ::ZlibCompressor, T)
	result = transcode(CodecZlib.ZlibDecompressor,a)
	_reinterpret(Base.nonmissingtype(T),result)
	end
	function zcompress(a, ::ZlibCompressor)
	a_uint8 = _reinterpret(UInt8,a)[:]
	transcode(CodecZlib.ZlibCompressor, a_uint8)
	end

It looks like the clevel field in the compressor is not accessed, even in zcompress? Not sure if this is intentional or I am missing something.
